A remand prisoner who failed to return to Maghaberry jail after he was given compassionate bail to attend a funeral has been arrested in north Belfast.
An armed support unit assisted detectives in the detention of James Valliday, 52, on Sunday morning.
A 29-year-old woman is also being held on suspicion of assisting an offender.
Police are still appealing for information about the whereabouts of a second missing remand prisoner, his brother Charles Valliday, 45.
The two brothers went on the run after failing to return to prison after attending a relative's funeral in west Belfast in November.
A court had granted them temporary release on compassionate bail.
The police are appealing to the public for information and have warned the public not to approach Charles Valliday as he has a history of violence.
A PSNI spokesperson said: "I would appeal to Charles Valliday to hand himself in without further delay."
Charles Valliday is 5ft 9ins tall, of stocky build, with short, brown hair, protruding ears and green eyes, police said.
