A 41-year-old man has been arrested by detectives in connection with a loyalist murder in Belfast.
The Ulster Volunteer Force (UVF) was blamed after Bobby Moffett was gunned down in broad daylight on the Shankill Road in May 2010.
The suspect was detained in west Belfast and taken to Antrim police station for questioning.
Moffett, 43, was a member of the UVF-allied Red Hand Commando terror group. He was shot by two masked gunmen.
A number of people have been arrested over his death but no-one has been charged. The International Monitoring Commission said the killing was sanctioned by the UVF.
His murder caused political ramifications by forcing the resignation of the UVF-aligned Progressive Unionist Party leader Dawn Purvis.
She was the party's sole representative in the Northern Ireland assembly but said she could no longer "defend the indefensible".
The UVF has carried out acts of decommissioning but the killing raised fresh questions about that process.
The suspect was later released without charge.
