Police have released CCTV images after a man suffered a serious assault on a train between Irvine and Kilwinning.

Officers from British Transport Police believe the men shown in the CCTV images may have information which could help with their enquiries after the assault on March 23 this year.

The victim – a man in his twenties – joined the 12.15am service from Glasgow Central to Ayr. As the train travelled between Kilwinning and Irvine another passenger was being verbally abusive.

The victim approached the man who was being abusive, who became immediately violent. He punched the victim in the face, causing him to bleed badly.

Other passengers then came to the assistance of the man who sustained a broken nose and broken teeth. The suspect then left the train at Irvine.

Anyone with information asked to contact British Transport Police by either sending a text to 61016 or call 0800 40 50 40 quoting reference 28 of 23/03/2018 or calling Crimestoppers anonymously on 0800 555 111.
