A 22-year-old man sustained a serious injury to his chest in what police are treating as attempted murder in West Lothian.

At around 5pm on Saturday, on Union Road, Whitburn, a man was assaulted with a weapon.

As a result, he sustained a serious chest injury and was taken to Edinburgh Royal Infirmary for treatment.

The suspect is described as a white male, aged between 18-25 years old, around 5ft 10 and of medium build. He had short brown hair and was wearing a dark-coloured jacket.

Inquiries into the full circumstances are ongoing and anyone with information is asked to come forward.

Detective Sergeant Graham Garvie said: "This was a vicious attack to a young man who has sustained serious injuries and we are eager to trace the man responsible as soon as possible.

"We know that there were a number of people in the area at the time of the attack and we are keen to hear from anyone who witnessed what happened.

"We believe the victim may have walked from the West Main Street area onto Union Road and I would ask anyone who saw him and the suspect prior to the attack to get in touch.
