Police investigating the murder of PSNI Constable Ronan Kerr have been granted a further six days and 18 hours to question a 33-year-old man who was arrested in connection with the killing last Friday.
Earlier this week, detectives were given another six days to question two other men about the murder of the 25-year-old officer.
Constable Kerr was killed when a bomb exploded under his car in Omagh on 2 April.
Elsewhere, detectives investigating dissident republican activity have recovered a number of firearms and ammunition in Lurgan, Co Armagh.
Two pistols, a shotgun and what police have described as a 'significant' amount of ammunition were found in the Tarry Drive area of the town earlier today.
No arrests have been made.
