The First Assistant US Attorney in the Central District of California, Bill Essayli, said Markle - the father of Meghan, Duchess of Sussex - "cut the bracelet" off at 1.45am on Tuesday (6.45am UK Time).
At a hearing in Tampa, US Magistrate Judge Lindsay Saxe Griffin, of the Middle District of Florida, ordered Markle to be detained and jailed without bond.
In court documents filed after his appearance, the judge wrote that "the defendant violated the conditions of his pretrial release and that, based on the lack of suitable housing, no condition or combination of conditions would reasonably assure the safety of any other person or the community and the defendant's appearance in court."
Markle had been arrested by federal law enforcement.
The prosecutor's office had earlier said it would be asking the court to revoke his release and remand him in custody, pending his trial over child abuse image charges.
Mr Essayli said: "Release conditions are court orders, not suggestions. We are asking the court to revoke his release and detain him pending trial, and we will continue to prosecute this case to the fullest extent of the law."
Markle's initial arrest on Friday followed the seizure of around 78 items, including slides, film negatives, and books that contained suspected child sexual abuse images in storage in the Los Angeles area, Mr Essayli said.

The Duchess of Sussex's father appeared in court last Friday after being arrested and charged with allegedly possessing child sexual abuse images.
The 82-year-old was pictured in handcuffs in a wheelchair as FBI agents escorted him from a retirement home.
He appeared at a short court hearing in Tampa, Florida, and was charged with one count of "possession of child pornography".
Hours later, a judge allowed Markle to be released on the condition that he would be electronically monitored, which generally means wearing an ankle tag.
Markle was living in the Philippines this year when he suffered a stroke and had his left leg amputated, forcing him to return to the US.
On Tuesday, Harry and Meghan arrived at the European Parliament in Brussels for their first joint public appearance since Markle's arrest.
Harry took to the podium to deliver a solo keynote address after the duchess pulled out of speaking alongside him because she was not "strong enough emotionally".
The 41-year-old man, who has not been named, was detained near Gloucester on Tuesday, on suspicion of offences under the National Security Act 2023.
He is being held over allegations in relation to section 1 of the act - obtaining or disclosing protected information, and section 3 - assisting a foreign intelligence service.
Sky News understands the senior soldier was stationed at Imjin Barracks near Innsworth, on the outskirts of Gloucester, where NATO's Allied Rapid Reaction Corps has its headquarters.
The Metropolitan Police said counter terrorism officers have been working closely with the FBI and US military in the investigation.
Kash Patel, the head of the FBI, said: "This important arrest involves allegations of espionage, which is of the utmost concern to the United States and our allies."
Officers are carrying out searches at two locations in Gloucestershire, the Met said.
The force added that the country to which the allegations relate is Russia.
The 41-year-old soldier remains in custody at a police station in London and the investigation is being led by officers from Counter Terrorism Policing London, as enquiries continue.
It is not linked to any other ongoing CTP investigations, police said.
Mr Patel added: "While this investigation is continuing, I want to send a clear message - this FBI has no tolerance for anyone who breaks their oath to the United States and whose actions endanger our national security and that of our partners."

Deputy Assistant Commissioner Vicki Evans, senior national coordinator for Counter Terrorism Policing, said: "This significant arrest and investigation is a result of close collaboration between UK and US authorities.
"The allegations are serious and our investigation is very much ongoing.
"This activity demonstrates the strength of our UK and US law enforcement and national security partnerships, and I commend the work of all the teams involved.
"We will work together to take robust action against those we suspect of any criminal activity that could undermine our national security."
Brigadier General Sean Stinchon, the commanding general of US Army Counterintelligence Command, said: "The alleged conduct of a senior soldier, entrusted with sensitive information, is a sobering reminder that insider threats are real and persistent.
"I encourage anyone who thinks they've witnessed something suspicious to report it to their local counterintelligence office."
On Monday, the disgraced comedian and actor, 51, was sentenced to 10 years and six months in prison, after being convicted of one count of rape and three counts of sexual assault.
Last week, it was revealed two further rape allegations against Brand were already being investigated and Metropolitan Police commissioner Sir Mark Rowley said he expected more victims to come forward.
A spokesperson for the force said on Tuesday: "Several people have contacted the investigation team during and since the trial to provide information or report a potential criminal allegation.
"Detectives are assessing this information as part of their ongoing enquiries."
Jemima Goldsmith, a British journalist and screenwriter and former girlfriend of Brand, posted on social media hours after he was sentenced to say she had personally experienced Brand's "violence, coercive control and abuse".
She said she was "in awe of the courageous women who came forward" during the trial, adding she helped the journalists who exposed him.
"I had to call the police to have him removed from my house in 2014 during a violent incident," she wrote.
Goldsmith said she chose not to press charges and go public as she was worried about the impact of press attention on her children.
"I am glad and relieved that Russell Brand has finally faced justice," Goldsmith said.
The pair dated for about a year in 2014, and Goldsmith said she has "neither seen nor spoken to Brand since that period".
The former head of Channel 4 News offered "personal thanks" to Jemima Goldsmith, saying she "alerted" her to Brand being a potential "danger to other women".
In a post on X, Dorothy Byrne said Goldsmith alerted her to Brand "because she believed, based on her own experience, he was a danger to other women and must be exposed".
Byrne told Sky News on Monday that a key reason she started an investigation into Brand - which the channel eventually aired as a Dispatches documentary in 2023 - was because she heard allegations that "led me to believe he was a danger to women who should be locked up".
Brand's convictions last week at London's Southwark Crown Court relate to offences committed against four different women between 2004 and 2009.
He was convicted of raping a woman in 2009. She told the court that after consensual vaginal sex, and without warning or consent, Brand anally raped her, leaving her in such pain she was unable to "speak or breathe".
Brand was convicted of sexually assaulting a female Channel 4 worker in 2009, shortly after he had started dating pop star Katy Perry.

The woman, who was working alone with Brand and his entourage, was forced to massage him, and at one point he knelt down and put his head in her lap, with his nose and mouth in her "vaginal area".
Brand was found guilty of sexually assaulting a woman at a bar in Soho in 2004, where he grabbed her breasts within seconds of meeting her. She was left "extremely upset and traumatised", the judge said.
Brand was also convicted for sexually assaulting a Choice FM worker in either 2004 or 2005. She told the court he kissed her "sloppily", groped her body, and laughed when she eventually managed to push him away.
Brand was acquitted of two other rape charges and one count of attempted indecent assault.
The 51-year-old had denied all the charges, claiming all the sexual contact was consensual as he pursued an extremely promiscuous lifestyle during the height of his fame.
Lieutenant Colonel John Harvey OBE was Gold commander of Operation Northmoor between 2016 and 2019, investigating whether UK Special Forces had committed war crimes in Afghanistan.
He told the Independent Inquiry Relating to Afghanistan on Tuesday that photographs of dead Afghan males with apparent gunshots to the head "didn't seem right".
But he conceded that, even though the images "cried out for examination", he had not had them sent to experts for further investigation.
Operation Northmoor, a £10m investigation set up in 2014 to examine allegations of executions by special forces, including those of children, resulted in no prosecutions.
The inquiry was shown photographs of 17 dead Afghan men identified in military terms as EKIAs (Enemy Killed in Action) killed during two separate Deliberate Detention Operations (DDOs) in February 2011.
Nine EKIAs could be seen in pictures pertaining to the first DDO on 7 February.
Each had signs of traumatic bleeding to the face or head. Many were lying next to what appeared to be pillows stained with blood.
Counsel to the inquiry, Oliver Glasgow KC, explained that the images are "copies of copies of copies" and therefore of a reduced quality but reminded Lieutenant Colonel Harvey that the photographs he had access to as Gold Commander were of JPEG quality.
The officer, who was awarded an OBE for his work in the role in 2020, the year he left the army, admitted he could have sent the higher-quality pictures.
Mr Glasgow brought up earlier evidence from an officer who was told by an SAS member that the force had a policy of killing all fighting-age males on sight, regardless of the threat they posed.
After conceding that the pictures made him think of that evidence, Mr Harvey conceded that the images "were never submitted".
Photographs of a DDO two nights later on 9 February show eight EKIAs, two of whom were lying in corners of the room, one on what appears to be bedding.
The pillow next to his head was heavily stained with blood and there was blood spatter on the wall.

Under questioning, Lieutenant Colonel Harvey accepted these details, along with the presence of "possibly some kind of blanket" across the chest of one of the EKIAs, could "potentially" suggest the pair were in bed, possibly sleeping.
The inquiry heard the photos had "cried out for examination" but were not sent on to experts.
That lack of further investigation, Mr Glasgow suggested, had "deprived all parties of potentially valuable information" that might have cleared special forces of any wrongdoing.
Mr Harvey agreed, adding that the only reason people would not want photographs to be examined was that "they don't want the answers to come out".
Police Scotland said the crash in Hyndland Road, in the west end of the city, happened at about 3.45pm on Tuesday.
