Missing Glasgow Woman's Mum Speaks Out
The mum of a deaf woman missing in Glasgow has thanked everyone who has helped in the search so far.
Kirsty Aitchison, 30, from the Robroyston area of the city, has not been in contact with friends or family since she left Campus bar in Sauchiehall Street at about 3am on Sunday.
She was on a night-out with friends and police say her subsequent disappearance is "completely out of character''.
Her mother Fay Aitchison said: "Whilst this is a very difficult time for us all as we wait in hope to hear from Kirsty, I would personally like to thank all her friends, family members and people from the Deaf community who have been busy raising awareness of the fact that my lovely daughter is missing.
"The sharing of information and searching areas for Kirsty is very much appreciated by us all.
"The police are speaking to us continually with updates on their search for Kirsty and we hope to have her returned to us safe and well as we miss her terribly.."
Police officers are speaking to friends and family and reviewing CCTV to figure out her movements until her last sighting on CCTV at the Broomielaw at 3.16am.
Inspector Stuart Clemenson from Greater Glasgow Division said: "Officers are continuing to carry out enquiries, review other CCTV footage and use specialist resources to search for Kirsty. We ask local communities to continue to help us by sharing the appeals, raising awareness and contacting us with any information they may have.
"Police Scotland has specialised, trained resources including search officers and the air support unit to support those community policing officers conducting enquiries.
"We're aware of speculation about Kirsty's movements however her last confirmed sighting is at the Broomielaw and we are currently focussing our efforts there and in the city centre.
"I would appeal again for anyone who may have seen Kirsty in the early hours of Sunday morning or who may know of her whereabouts to get in touch on 101 or to email email@example.com."
