Fresh footage has been released amid a frantic search for a vulnerable Glasgow man.

Alexander Marshall has been reported missing from his home on Novar Drive in the city's Hyndland on Wednesday, November 27.

We reported that his family are extremely worried as the 75-year-old has dementia and is thought to be travelling without his medication. 

(Image: Police Scotland) Alexander, who is also known as Sandy, was last seen at a shop on Argyle Street at Glassford Street at around 1pm, then in the Queen Street Station area around 1.45pm.

Cops are scouring CCTV from the area and have released another image of him.

They are urging anyone who spots him to get in touch, particularly on buses and trains as he is known to take these modes of transport. 

He is described as around 5ft 8ins tall and of slim build with short, grey/white hair and a beard.

As can be seen in the image, Alexander was last seen wearing a grey jumper, brown gilet, blue jacket, blue jeans, brown shoes and a black hat.

Inspector Kevin Dougall said: “Given the period of time Mr Marshall has now been missing and the cold weather conditions, we are very concerned for his safety and wellbeing.

“His family are extremely worried and just want him home safe and well.

“Enquiries and searches are continuing to trace him. Officers are reviewing a wide range of CCTV from where he was last seen in Glasgow City Centre to establish where he headed from there.

“We are grateful for any assistance from the public in sharing our appeal and reporting any sightings or information that may help.

"I would also urge people living locally to the Hyndland and Patrick areas to check any sheds or outbuildings in case he was making his way home and sought shelter there.

“If you have any information that may help us trace Alexander, please contact 101 quoting reference number 1101 of November 27.”
