POLICE are offering a reward of £5000 for information leading to the arrest and conviction of the man responsible for a rape in Peterborough.

The rape happened on Tuesday, May 19, 2009 on a cycle path which runs parallel to Gresley Way, Westwood.

A 27-year-old woman was attacked as she walked to work at around 3.20am.

The attacker grabbed her from behind and forced her to the floor. He then strangled the victim causing her to fall unconscious before sexually assaulting her.

The reward is being offered after a mass DNA screening of men has this far failed to identify the attacker.

307 men have so far volunteered a sample of their DNA to police.

The samples were then profiled and 107 were sent away for further analysis to establish if they match the attacker.

Detective Inspector Simon Harding said: "We are now offering the reward as a further incentive to encourage anyone who may have information about this attack to come forward.

"We believe there may be someone out there who has information which could prove vital in bringing the man responsible to justice."

The reward will come from police funds and it is due to the seriousness of the offence that this unusual step has been taken.

As the investigation into the rape continues police have also released a new CCTV image of a man they would like to speak to in connection.

The moving images show the man walking along Taverners Road at the junction with Clarence Road heading towards Westfield Road at 3am on May 19.

DI Harding added: "We appreciate that you can't see the man's face clearly however someone may recognise the clothing or the way that he walks from the moving images.

"Someone may even be aware of a person who takes this route regularly at that time of the day.

"We would like this man or anyone who thinks they know him to come forward as he may hold vital information."

Anyone with information should contact Cambridgeshire Police on 0345 456 456 4 and quote "Operation Mile.

Anyone who wishes to give information anonymously can do so by contacting Crimestoppers on 0800 555 111.
