Police searching for a young lad missing after a night out in Glasgow have stepped up their appeal as concerns grow over his welfare.

Officers say his family is fearful after the "out of character" disappearance and are urging anyone with information to get in touch.

Lewis Simpson was last seen on Montrose Street in the city centre at around 1am on Sunday after a night out with friends at the Strathclyde Student Union.

He hasn't been in contact with any family or friends since, which police say is very unusual for him.

He is described as being 5ft8ins tall, of a slim build with short blonde hair and a fair complexion.

At the time he went missing Lewis was wearing a black jacket (pictured), black jeans and brown shoes. 

Inspector Aidan Higgins, of East Kilbride Andrew Street police station, said: “Along with his family, we are becoming increasingly concerned for Lewis’ welfare. It is very out of character for him to be out of contact with family. 

“We would urge anyone who may have seen Lewis to contact us.

"Similarly, if Lewis is reading this, I appeal to you directly to let us or your family know you are safe and well.” 

Anyone with information is asked to contact Police Scotland on 101, quoting incident 0364 of Sunday, February 23.
