POLICE have spoken to 70 people during anniversary checks to near the scene of a sexual assault in Ipswich.

Officers returned to the scene, at the Regent Theatre car park, in St Helen's Street, between 11pm yesterday to 4am today.

They approached people in Great Colman Street, Northgate Street and Old Foundry Road, hoping they were in the area a week earlier.

Lisa Miller, southern area communications officer for Ipswich police, said: "About 70 people were spoken to during the course of the checks.

"Police would like to thank members of the public for their co-operation during the course of these checks.

"The information gathered will now be looked at in detail to see if it helps move the investigation forward."

At approximately 1.15am, on February 10, a 31-year-old woman and her friend made their way to the taxi rank, in Old Foundry Road, after a night at Shout nightclub, in Northgate Street.

The friend got a taxi and while the victim waited for another one to come two men approached her.

They then dragged her to the Regent Theatre's car park where both men subjected her to a serious sexual assault.

Despite numerous appeals police are still wishing to speak to the person who helped the victim when she called her friend from the kiosk at around 3.30am.

It is believed that this man was driving a light coloured Nissan Primera car.

Police say he is a vital witness and not a suspect and any phone call made by him would be treated in the strictest of confidence.

Anyone with any information to this incident should contact detective inspector Stuart McCallum at Ipswich CID on 01473 613500.
