Police have released CCTV images of a man that officers would like to speak to in connection with a sexual assault in Oxford.

At around 10.23pm on Sunday December 12, an 18-year-old woman was walking down Hythe Bridge Street with a friend in the direction of Oxford Train Station.

They stopped outside the Lung Wah Chong Chinese Supermarket where the offender has approached them.

The offender touched the victim inappropriately over her clothing.

The victim and her friend then ran off to Sainsbury's on Park End Street and were followed by the offender.

The offender remained outside Sainsbury's so the victim and her friend asked a member of staff at the store to accompany them to the train station as they didn’t feel safe.

The offender followed them to the station before being spooked by staff and running off.

Investigating officer, PC Cameron Woods, based at Cowley police station, said: "We are releasing CCTV images of a man we believe may have vital information in relation to this incident.

“If you recognise the man in the images please call Thames Valley Police on 101, quoting the reference 43210561162.

“Alternatively you can make a report online or call the independent charity Crimestoppers 100% anonymously on 0800 555 111.”
