High-profile Belfast loyalist Mark Haddock has been "reported for prosecution" over three sectarian murders.
The 45-year-old was arrested in England yesterday by detectives investigating the 1994 killings by the UVF.
Workmen Gary Convie (24) and Eamon Fox (44) were in their car at a building site in North Queen Street in Belfast when a gunman opened fire with a sub-machine-gun.
Sean McParland (55) was shot in Skegoniel Avenue in Belfast on February 17, 1994 while babysitting. He died a week later.
Haddock, originally from the Mount Vernon estate, was detained by the PSNI and questioned at Newbury police station in Berkshire.
