As homelessness increases across Britain, caring Glaswegians are voicing their concerns just a day after a man was found dead on a busy city centre shopping street.

The vacant BHS building on the corner of Renfield Street and Sauchiehall Street has now been spray-painted with the terms ‘No more homeless deaths’ and ‘Let the people in’.

The markings came after police and paramedics were called to TJ Hughes on Trongate early on Tuesday morning where they found a man slumped outside the department store.

He was pronounced dead at the scene.

A police spokeswoman said the death was being treated as “unexplained.”

“It is not thought to be suspicious,” she added.

The images were posted onto Twitter by user Caitlin Rose on Wednesday who said: “After a homeless man froze to death in Glasgow, this is plastered into BHS.

“Make it happen.”

She added: “I say a man but he was only 20, and had been homeless since he was 16.

“It’s not bloody right.”

It has not been officially confirmed by police whether the deceased man was homeless or not, or how he died.

The post, however, has been well-received, having racked up close to 3,000 likes and over 1,600 retweets so far.

According to Shelter Scotland, in 2015/16, 34,662 homeless applications were made.

Around half of all homeless households are headed by someone aged under 30, said the housing charity.

“Female homeless applications are typically younger, with more female applicants than male in the under 25s,” Shelter said.

Deputy director, Alison Watson, has said: “At the heart of the problem is Scotland’s housing crisis caused by an acute shortage of affordable homes.

“We recognise the Scottish Government’s commitment to build 50,000 new affordable homes by 2021, but that falls short of the minimum of 12,000 a year we actually need.”
