 The students have had to be re-housed because of the problem |
Around 30 students were evacuated from their home in Sheffield because of fears the building could collapse. Firefighters were called to the block of flats in Edward Street at 0830GMT on Sunday by South Yorkshire Police who feared for the structural safety of the building.
The area has been sealed off and surrounding buildings have been evacuated as experts conduct an investigation.
The students from Sheffield's Hallam University were taken to Nelson Mandela building before a process of re-housing could be organised.
A team of structural engineers are examining the site after ground at the rear of the building collapsed, putting the foundations of the flats in jeopardy.
South Yorkshire Police were alerted to the problem at 0742GMT by a passer-by who said a wall, approximately 20ft square had collapsed on Edward Street.
The fire and rescue service arrived at 0830GMT and the students were moved out.
Jim Greaves duty officer for South Yorkshire Fire and Rescue Service in Sheffield told BBC News Online: "Four buildings under threat from collapse, one of which is in very serious danger.
"This is due to a collapse of earth underneath part of the student accommodation.
The reason for collapse is a matter for investigations by the Health and Safety Executive and Sheffield City Council's dangerous structures dept.
Mr Greaves said the gas supply to the flats was also being sealed off.
