Reward of £5,000 in hunt for Cambridge sex attacker
A £5,000 reward is being offered for information leading to the arrest and conviction of a Cambridge serial sex attacker.
The charity Crimestoppers has put up the money.
Police believe the same man has sexually assaulted eight women in Cambridge since August 2010.
An e-fit image of a man the police want to trace has been released and 100 men have been eliminated from the police inquiry.
The first attack happened at 0115 GMT on 11 November, when a 21-year-old woman was grabbed in Adams Road.
The most recent was on 7 March in the Mill Pond area, Mill Lane, at about 2300 GMT when a woman in her 20s was assaulted as she walked home.
A man rode up on a bicycle and grabbed her before riding off.
In every incident the offender has run off when the victim began struggling or screaming.
Det Sgt Phil Priestley said: "We believe that the e-fit is a good likeness of the offender and it has already helped us identify another victim.
"I would urge anyone who recognises the image to contact police or anonymously via Crimestoppers."
