The owner of a care home where four staff were arrested over allegations of ill treatment has decided to close it to all residents.
Leicester City Council had already decided to terminate its contract with Fosse Court owing to "concerns about care quality" and is moving out the residents it funds.
Residents paid for privately will now also need to leave.
Owner Fosse Court Limited accused the council of overreacting.
The company remains registered with the Care Quality Commission (CQC) and the home could reopen in future, but a spokesperson said they "don't know" yet if the closure will be permanent.
Its statement said: "As a responsible care provider we have taken the very difficult decision to close Fosse Court.
"We do not believe that there is an alternative course of action due to the overreaction and inappropriate pressure applied to the home by Leicester City Council and CQC, which 42 days ago found the home to be compliant with most of the regulations inspected.
"The high standards of care that we demand cannot be delivered while the concerns raised are looked into and a police investigation is ongoing.
"We have not taken this decision lightly as the welfare of our residents is paramount but we firmly believe that this is the right thing to do."
Leicestershire Police confirmed earlier this week that officers had arrested and bailed four female staff members from the home following allegations of ill treatment and an inspection by the CQC.
A spokesman for Leicester City Council said: "We are moving residents out of Fosse Court because we are terminating our contract over concerns about care quality.
"The owner has also now advised us that he has taken the decision to close Fosse Court as a business.
"We are doing our best to move residents in line with their choices and those of their relatives, as best we can given the short timescale."
