Police officers are now searching an industrial estate near Dawsholm Park where missing student Karen Buckley’s handbag was found.
Officers have also been seen with shovels in Dorchester Avenue in Kelvindale, and a back lane and woodland area near the canal has been sealed off.
Forensic teams have also been scouring a garden and an air support unit, marine policing underwater unit, specialist crime division, police search dogs and operational patrols are all now assisting in the search for Karen, who went missing three days ago.
Karen (24) from Cork in Ireland, was last seen walking away from a nightclub in Glasgow’s west end just after 1am on Sunday after talking to a man outside.
The Glasgow Caledonian University student had been at Sanctuary nightclub on Dumbarton Road in Partick from about 11.45pm on Saturday night.
At about 1am she told friends she was going to the toilet but she didn’t come back and didn’t pick up her jacket.
CCTV cameras captured images of her talking to a man outside the club, then she left and walked towards Church Street.
She went, consensually, with a man to a flat in Dorchester Avenue, Kelvindale, and left at around 4am alone.
Detective Superintendent Jim Kerr said: “Our absolute priority is to find Karen. We have a team of specialist search officers from the west and east working in the area as well as additional patrols in the west end and north of the city.
“Anyone with any information, no matter how insignificant it may seem, should contact 101 or anonymously on Crimestoppers.”
The police are also still keen to trace the driver of a grey/silver car which was seen in country roads between Milngavie and Drymen between 11am and 3pm on Monday.
Officers have stepped up patrols in the west end, Kelvindale and Anniesland. Members of the public are being urged to approach them with any information or any concerns they might have.
