A 23-year-old man has been released after he was questioned about a claim of responsibility made for the shooting of one of Northern Ireland's top detectives.

Det Ch Insp John Caldwell suffered life-changing injuries after he was shot in front of his young son in Omagh on 22 February.

The man was arrested after the search of a property in Londonderry.

He was taken to Musgrave Police Station in Belfast for questioning.

An admission of responsibility for the shooting was made in a typed statement taped to a wall beside shops in the Creggan estate in Derry.

Police believe the dissident republican group the New IRA was behind the attack.
