Two held over Carroll murder

The men, who are in their 20s and 30s, were questioned at Antrim police station on Tuesday.

It's thought the men are well-know dissident republicans in the Craigavon area.

Carroll, a 48-year-old police man, was gunned down answering a distress call in Lismore Manor on March 9 last year. He was the first police officer to be killed by paramilitaries since the PSNI's formation in 2001.

Shortly after the incident a 38-year-old former Sinn Fein councillor and a 17-year-old were arrested and are still on remand for the killing.

Last week a 40-year-old man was detained in Lurgan while another man aged 36 and a 37-year-old woman were arrested in the Craigavon area last Tuesday morning (February 9).

The trio were later released without charge.

Constable Carroll was shot dead by dissident republicans while on duty last year two days after the Real IRA killed two soldiers outside Massereene Barracks in Antrim.
