A man has been arrested on suspicion of the 1995 murder of Ian Grant.
Ian Grant's body was discovered on wasteland near Fulbourn Hospital close to his Cherry Hinton Home on November 15th 1995. It is thought he was killed the night before.
A 49-year old man was arrested in Cambridge this morning.
Cambridgeshire Police say the man has not previously been arrested in connection with the investigation.
The case was re-opened last week after new evidence was uncovered.
