People evacuated from their homes in a flooded Lincolnshire town will not be able to return until at least Monday.
More than 580 homes in and around Wainfleet were evacuated after heavy rains led to the River Steeping bursting its banks last Wednesday.
Those affected were previously told they may be able to return on Friday.
Ch Insp Phil Vickers, from Lincolnshire Police, said “a more permanent repair” on the breach needed to be carried out before it is safe for people to return.
“We know it’s hugely frustrating for those local residents and so we’re looking to get them back to their houses as soon as we can.
“But at this stage we can’t guarantee that safety and so the evacuation warning remains in place.”
