Police said a woman in her 30s was sexually assaulted in a parking lot after getting into her car.
Sussex Police said the victim was in Bognor Regis town center, West Sussex, on Thursday evening when she got into a car near the Tesco supermarket on Station Road.
Police said the vehicle, believed to be silver or gray, stopped at a makeshift bus stop on the A259 near the junction with Marsh Lane in Merston before sexually assaulting the victim sometime between 23:30 GMT on Thursday and 01:00 GMT on Friday.
The driver is described as a South Asian man in his 30s or 40s with short, dark, curly hair.
Police said the victim fled to safety before reporting the incident.
Police are keen to trace anyone who may have been in the Station Road area near Tesco, or anyone who may have seen the vehicle as it left Bognor Regis.
Arran and Chichester area commander Inspector Adam McCaig said: “We will continue to work closely with our partners as the investigation progresses and will have officers conducting additional patrols in the area over the weekend to provide reassurance.”
Anyone with dash cam or doorbell camera footage is asked to contact police.
