Police in the North have appealed directly to a convicted murderer on the run to hand himself in.
Thomas Valliday, 27, has been at large since escaping from prison staff during a hospital visit on Friday.
Officers said they are following up on a number of reported sightings of the killer. Valliday is a life sentence prisoner at Maghaberry high security prison in Northern Ireland.
He was convicted in 2010 of the murder of west Belfast republican Frank “Bap” McGreevy.
The killer, also from west Belfast, was handed a minimum 17-year life tariff.
He escaped while attending the Ulster hospital in Dundonald on the outskirts of Belfast.
Police Service of Northern Ireland (PSNI) Detective Inspector Harry Colgan said: “Police are conducting extensive enquiries into the whereabouts of Mr Valliday and we will continue to do so.
“We will use all appropriate and available resources available to assist us in detaining Mr Valliday and to bring him before the courts.
“A number of sightings of the prisoner have been reported to us by members of the public and we are following up on each of those reports.
“I urge the public not to approach Mr Valliday as he has a violent history and is considered dangerous but I would ask that any sightings or information as to his whereabouts are reported immediately to the police.”
Mr Colgan added: “I would like to appeal directly to Thomas Valliday to hand himself in to the authorities without any further delay.
“This is the right thing to do and by doing so he can help to reduce the impact and upset that he is causing to his family, friends and the wider community.”
