A woman was sexually assaulted at a bus stop in the centre of Helensburgh at the weekend.

According to police, the woman was chatting to a man at the bus stop at Maitland Court, opposite Helensburgh Central railway station, at around 10.40pm on Friday, November 19 when, after a short time, he tried to kiss her.

When she rejected him, police say he sexually assaulted her before walking off.

The suspect is described as white, 6 ft 2, of heavy build, with ginger hair and beard. He was wearing all black clothing; jeans, jacket and trainers.

Detective Constable Ross Gemmell from Clydebank CID said: "Although the woman did not require medical treatment, she was left very shaken by what had happened.

"We are following lines of enquiry with regard to the person responsible but are still appealing to anyone who may recognise the description of the man or who may have seen what happened to come forward.

"The area would have been quite busy at this time of night, so if you have any information that may assist our enquiry, then contact officers at Clydebank CID via 101."

Anyone contacting police with information about the incident is asked to quote incident reference number 4249 of Friday, November 19.

Alternatively, details can be provided anonymously to Crimestoppers on 0800 555 111.
