Police are investigating a care home over safeguarding concerns.
Cornwall Council has removed its residents of Sunningdale House in Perranporth after concerns were raised over the quality of care.
Devon and Cornwall Police said: “We are in the early stages of what is likely to be a protracted and fairly complex investigation.”
The owners of Sunningdale House, South West Care Homes, have replaced the home’s management team.
The company said the home remained open but added: “Care wasn’t reaching its usual high standards.”
The police inquiries are part of a joint investigation with Cornwall Council Adult Safeguarding Services.
In a statement the council said it had “taken the decision to find alternative care provision for the residents it funds at Sunningdale”.
It added: “We are working closely with families and partners and support is available for those people who fund their own care if they wish to move.”
The council would not give any further details about what prompted its actions.
Inspectors from the Care Quality Commission (CQC) have visited the home twice in the past month.
Sunningdale House, which overlooks the boating lake in Perranporth, was rated “good” by the care watchdog in July 2017.
South West Care Homes said: “We are now working with the CQC and the council to reassure them that the quality of our care has returned to our exacting criteria.”
A CQC report is expected to be released in the coming weeks.
