An e-fit of a man who tried to force a woman into a vehicle in Cheltenham has been released.
Police said the 26-year-old woman was walking on Hewlett Road when the man grabbed her in the early hours of 14 November.
He tried to force her into the vehicle but she managed to get away.
The man drove off. He is described as white, clean-shaven, in his late 30s, and was wearing jeans and a dark jumper.
The Gloucestershire Constabulary spokesman said the woman suffered minor injuries to her hand.
'Shaken and upset'
Police are trying to trace a possible witness who drove into Duke Street about 0345 GMT and might have seen the attacker driving with no lights.
The type of vehicle he was in is not known, the spokesman added.
Investigating officer Det Con Andy Halford said: "Fortunately the woman was not seriously injured but she was left very shaken and upset.
"Incidents of this nature are extremely rare in the town and we are doing all we can to trace the offender.
"People should not be unduly worried, but we would like to take this opportunity to remind people to consider their personal safety.
"If you are out late at night try to avoid walking alone and stick to well-lit routes."
