Three people are being questioned in the North about the murder of a policeman in Armagh last year.
48-year-old Stephen Carroll from Banbridge in Co. Down was gunned down as he answered a call-out in Craigavon last March.
The Continuity IRA claimed responsibility for his death.
Earlier, two men aged 36 and 40 were arrested, along with a 37-year-old woman.
