Transport cops are appealing for information after a young man was brutally beaten at Ayr train station at the weekend after a group of men harassed his girlfriend.

The 21-year-old victim was hospitalised after the incident where he required multiple stitches to a deep facial cut.

The father of the victim, who asked that no names be reported, posted an image online of his son’s injuries online.

Writing on Sunday, he explained: “[My son] came off the train at Ayr station about 11.50pm last night with his girlfriend after a night in Glasgow and was attacked by three men, two in their 30s and one mid-50s, who had all been on the train since it left Glasgow.

“The police are looking through CCTV footage to try and identify the culprits. [I] hope that someone witnessed it.

“His girlfriend tells me at least 30-40 folk came off the train with them and most must have seen it, but a lot of them were returning from the Little Mix concert with kids so didn’t get involved, which is understandable.

“But, now’s the time to say something. He’s not a bad lad by any means and certainly ain’t a troublemaker as anyone that knows him will tell you.”

Detectives from British Transport Police (BTP) are now looking to the public for help in catching the perpetrators.

A BTP spokesman described how the victim joined the 11pm ScotRail service with his girlfriend at Glasgow Central heading towards Ayr.

As they attempted to leave the service at Ayr, the man’s girlfriend was harassed by a group of men.

The victim asked the group of men to stop, at which point one of the males then punched the victim multiple times on the head.

The suspect and the other men then made off from the scene.

The victim was then taken to hospital for treatment.
