Police have launched an appeal aimed at diners in a McDonald's restaurant in a bid to trace a vulnerable teenager.

Thomas Lennox, 19, of Airdrie was last seen leaving Hairmyres Hospital around 7.20pm on Friday June 8.

Officers have now confirmed a sighting of Thomas on CCTV walking along Victoria Road, Glasgow around 2.30am on Sunday June 10.

Thomas is believed to have been talking to people outside.

Inspector Aidan Higgins said: "We are asking members of the public to think back and remember where they were between 1.30 am and 3am on Sunday 10 June 2018.

"You may have been at the Beyonce and Jay-Z concert on Saturday evening or have been returning home from a night out in Glasgow.

"Did you see or speak to a man matching his description?

"Were you at McDonalds restaurant around that time , do you remember Thomas being at the restaurant?"

The officer also appealed to anyone who may have been driving in the area and may have seen something or captured Thomas on a dashcam.

Inspector Higgins added: "Thomas has mental health issues and has no medication with him or access to money.

"He has not made contact with any family or friends which is out of character , his family is desperately worried about him.

"As time goes on we are becoming increasingly concerned as to his wellbeing."

Anyone with information regarding Thomas's whereabouts is asked to contact East Kilbride Police Station via 101, quoting incident number 3972 of Friday 8 June 2018.
