DETECTIVES investigating the 21-year-old murder of a Gwent private detective who was about to expose police corruption made six arrests.

Daniel Morgan, 37, originally of Cwmbran, was found in a pub car park in Sydenham, south London in 1987 with an axe embedded in his head.

His family maintained he was killed by a professional hitman.

Police said today that five men have been arrested for his murder.

A sixth man - a serving PC - has been arrested on suspicion of misconduct in a public office.
