Raphoe man McDermott, who escaped from jail last week, was found in Derry.
He appeared in court again today charged with criminal damage and assaulting police officers during his arrest at Altcar Park in the Galliagh area of Derry.
He was sentenced to four months in prison. Gardai will then extradited him back across the Border when he completes that sentence.
McDermott, 26, had been on the run after escaping from Loughlin House low security prison in Co Cavan.
It is now believed that Gardai will issue the warrant so that the Donegal man can continue to serve his sentence in the Republic.
He may also face further charges for escaping jail and will probably be moved to a more secure prison.
Justice Minister Alan Shatter’s office has promised a full investigation into McDermott’s escape from Loughlin House.
McDermott, who was serving a seven year sentence for the manslaughter of Garda Gary McLoughlin in 2009, became abusive when he appeared in Derry Magistrate’s Court last week.
He called Judge John Meehan a “f******* w*****r” after the judge had refused him bail.
McDermott, 26, was quickly removed from court but later returned and apologised to Judge Meehan.
He was fined a further £150 for misbehavior in court and was ordered to appear again by videolink today.
Despite having a litany of more than 90 offences, McDermott was interred at the low security open prison after being found guilty of the manslaughter of Garda McLoughlin form Leitrim.
The tragic Garda was killed after the car in which McDermott was during ploughed into a Garda patrol car at Burt in 2009.
McDermot, who was found to be drunk, was being pursued y detectives after being observed acting suspiciously.
