The PSNI has issued a public appeal for help in locating 55-year-old convicted murderer Thomas McCabe, who is currently unlawfully at large.
McCabe, originally from Northern Ireland, was sentenced to life for the 1990 murder of a teenager in London and later released on licence.
His licence was revoked after a number of breaches and he previously went on the run after failing to return to Maghaberry prison.
Detective Constable William Arnott said: "McCabe, who was sentenced to life for murder, was released from prison on licence.
"However, following a number of breaches his licence was revoked in January 2018.
"He is described as around 5ft 8in tall, of medium build with short grey-coloured hair. We believe he has connections to Newry, Newtownabbey and Dublin.
"I would appeal to anyone who has seen Thomas McCabe or who knows of his whereabouts to contact us on 101.
"I would also appeal directly to him to hand himself in.
"Alternatively, information can also be provided to the independent charity Crimestoppers on 0800 555 111."
McCabe was convicted of murdering teenager Richard Hunt, whom he beat to death with a scaffold pole in London in 1990.
He had come home around 10.30pm in a drunken state to find Hunt there with his girlfriend. However, the victim was his girlfriend's cousin and had only been around to help out with decorating.
Sentenced in England, he was later transferred to Northern Ireland to serve out his jail term.
McCabe has absconded several times previously and been repeatedly suspended from a pre-release programme over concerns about his inability to comply with conditions and fears he would commit further violent offences.
