A road in Glasgow city centre has been closed after a sinkhole opened up with water running underneath the surface.
North Frederick Street near George Square was shut on Monday after police were called to the scene.
A Glasgow City Council roads inspector investigated and found running water under the tarmac.
Scottish Water was called in amid concern that a mains pipe had burst, but no issue with the network in the area could be found.
An assessment of the sewer system is underway to establish if it is the cause of the crater.
A Scottish Water spokesperson said: “We are carrying out further checks today to establish that our sewer network infrastructure in the area is working as it should. We are continuing to liaise with Glasgow City Council.”
Drivers have been advised to find an alternative route as an eastbound lane on George Square remained closed on Tuesday afternoon.
The council said it was treating it as a priority.
A Police Scotland spokesperson said: “Around 9.55am on Monday, October 18, officers were called to a report of a hole in the roadway on George Street at North Frederick Street, Glasgow.
“Officers attended and the road was closed while the relevant agencies deal with this matter.”
