Convicted child killer John Clifford, who was unlawfully at large from Maghaberry, has been arrested by police in the Newry area.
Clifford had been on the run for over a week, after failing to return from day release to attend an appointment.
He is now being returned to prison.
PSNI Detective Inspector Michael McDonnell said: “I would like to thank our An Garda Síochána colleagues for their assistance in locating Mr Clifford and facilitating his return to Northern Ireland.
“I would also like to thank those members of the public who contacted us with information and the media for their assistance in publicising our appeals for information.”
