Part of a South Wales car park has collapsed forcing nearby flats to be evacuated while officials try to fix a 10ft-wide crater, according to the local council.
No one was injured when the 12ft-deep hole appeared behind two blocks of flats in Brynmair Close, Aberaman in Rhondda Cynon Taf, in the Valleys.
Engineers are searching for the cause of the collapse, which saw the three flats nearest the hole evacuated. Residents are unlikely to be able to move back for two days.
Rhondda Cynon Taf Emergency Planning, Highways, land reclamation and structural engineers were all at the scene, according to a spokesman for RCT homes, which owns the flats but not the residential car park.
He said the hole was filled with water at the bottom but did not believe it was caused by frozen pipes or bad weather over the past few weeks.
Nigel Wheeler, service director for street care at Rhondda Cynon Taf Council, which owns the car park, said the hole had grown overnight and council staff were searching for its cause.
â€œUntil we have established that, we are not in a position to make effective, safe repairs,â€ he said.
