A man is fighting for his life in hospital after he was stabbed at a train station just outside of Glasgow.

The victim suffered a single stab wound following the altercation with another man at Westerton railway station in East Dunbartonshire at 1.15am on Sunday.

The victim remains in hospital, where he is receiving treatment to "life-threatening injuries".

Descriptions of three men and a woman have been released as transport police attempt to establish the exact circumstances of the attack.

Officers also wish to speak to a taxi driver who dropped the attacker off at the station just moments before the stabbing.

DC Lorna White, from British Transport Police, said: "This was a very serious incident and we are urgently appealing for witnesses to get in touch.

"In particular, we are keen to trace the driver of a dark-coloured taxi which dropped off the suspect at the station just moments before the assault at approximately 1.15am.

"If you were this driver, or were near to Westerton station, please get in touch as soon as possible."

If you have any information, call 0800 40 50 40 or Crimestoppers anonymously on 0800 555 111.
