​Kirsty Aitchison hasn't been seen since leaving the Campus Bar at 3am on Sunday morning

Police have issued an appeal in British Sign Language in an attempt to trace a missing mother of four who is deaf.

The appeal has gone out to Scotland’s deaf community to be on the lookout for Kirsty Aitchison, 30, from Glasgow who was last seen leaving the Campus bar in Sauchiehall Street at about 03:00 on Sunday.

Kirsty's family are concerned by her disappearance which is reported to be completely out of character for her.

She was part of the Scotland Deaf Booze Crew – a Facebook community which holds drink-fuelled night’s out for those with hearing problems.

One posting on the Facebook page reads: “I saw her loads of times outside smoking and drinking. She was looking like she had too much to drink. Hope she’s ok and safe home soon.”

Kirsty is described as having long dark hair, 5ft in height and of a slim build.

She was last seen wearing a black crop top, a cream mid length skirt and black heels.

Insp Leigh McManus, of Police Scotland, said: "Kirsty hasn't been missing before and it is completely out of character for her not to keep in contact with her family and friends. She was reported missing to police on Sunday afternoon.

"Officers are carrying out extensive inquiries to trace her, and I would ask anyone with any information on her whereabouts to contact Shettleston Police Office through the non-emergency number 101."
