A 31-year-old man has been arrested by police investigating the murder of journalist Martin O'Hagan.
The man handed himself into police at Antrim on Wednesday.
Earlier, Drew Robert King, 40, from Moss Road, Waringstown, was remanded in custody at Craigavon Magistrates Court charged with the murder.
Two men have already been charged with murdering Mr O'Hagan. A 28-year-old man is still being questioned by detectives about the killing.
Mr O'Hagan, 51, was shot dead as he walked home from a pub in Lurgan, County Armagh, with his wife in September 2001.
Mr King was remanded in custody to appear in court again on 10 October.
Mr O'Hagan, who worked for the Sunday World newspaper, had built a reputation for stories about paramilitaries and drug-dealing.
