Mr Mangione was denied bail for a second time on Tuesday, after prosecutors said he was too dangerous to be released.

The judge then gave prosecutors 30 days to seek a warrant from New York Governor Kathy Hochul to secure his extradition to the state.

Hochul later said she would provide one. “I am co-ordinating with the District Attorney’s Office and will sign a request for a governor’s warrant to ensure this individual is tried and held accountable,” she said.

Defence lawyers also have a two-week window in which to submit motions against Mr Mangione being moved to New York. The challenge was described by a Pennsylvania prosecutor as creating “more hoops… to jump through”.

Mr Mangione looked around at the rows of reporters in court and smiled at times. At one point, he interrupted his own lawyer, who quickly quietened him.

Following the hearing on Tuesday afternoon, that lawyer, Thomas Dickey, spoke to reporters outside court. “You can’t rush to judgement in this case or any case,” he said. “He’s presumed innocent. Let’s not forget that.”

Mr Mangione has been charged with several offences in Pennsylvania, including providing fraudulent identification to police and possessing an unlicensed firearm. He is being held at a Pennsylvania state prison and will plead not guilty.

In New York, he faces separate charges including murder for Mr Thompson’s killing on 4 December.
