Police in the North have arrested another man in connection with the murder of Sunday World journalist Martin O'Hagan in Co Armagh seven years ago.
The 28-year-old was detained yesterday by officers conducting a retrospective review of the killing.
A 40-year-old man who was arrested in connection with the case last Friday also remains in PSNI custody.
Mr O'Hagan, who wrote a series of articles investigating paramilitary activity, was shot dead by loyalists while walking home from a pub in Lurgan with his wife in September 2001.
Two men were charged with his murder last week, while another two men were charged with lesser related offences.
