A woman has been indecently assaulted in Bradford-on-Avon.
The attack happened on the riverside walk in the town at 2130 BST on Friday.
A man who had been walking in front of the 30-year-old local woman stepped out from some bushes near the swimming pool and exposed himself.
He then indecently assaulted her and ran towards the direction of the Riverside Inn after she pushed him away.
The offender is described as between 18 and 20 years old, of medium build with short dark hair.
He was wearing a baseball cap, baggy white shirt and blue jeans.
Police are keen to hear from a group of 10 youths who were seen walking along the path before the attack.
