Lothian and Borders Police are appealing for witnesses following a serious sexual assault in West Lothian last weekend.

The incident happened between 3.20am and 3.45am on Saturday 23 February 2013 in Livingston.

A 28-year-old woman was walking her dog and had just cut through an underpass at Grange Road at the east side of Perth Street, Craigshill, Livingston when a man attacked her.

She fell to the ground and was attacked before the suspect made off.

She returned home before attending at St John’s Hospital and contacting police.

Officers are now urging anyone who can assist with their enquiries to come forward.

The suspect is described as being white, small build, 25-40-years-old, with collar-length black/brown hair and was wearing a dark-coloured fleece, a dark-coloured beanie hat with a silver line, and white canvas trainers. He spoke with a Scottish accent and smelt strongly of body odour and alcohol.

Detective Inspector Matt Paden said:-“This has been a horrific attack for the victim to endure and she is now being offered all the support and assistance she requires from Lothian and Borders Police and our partner agencies.

“We are keen to speak with anyone who was in or around the underpass in the Perth Street area in the early hours of Saturday morning and remembers seeing anything suspicious.

“We are particularly keen to trace a witness who may have been in the area with two dark Labrador-type dogs and would ask this individual to contact police immediately.

“Similarly, anyone with any other information that can assist with our enquiries is also asked to get in touch.”

Anyone with any information can contact Lothian and Borders Police on 101 or the charity Crimestoppers in complete anonymity on 0800 555 111.
