A police investigation has been launched into abuse allegations at Terrys Cross House in Woodmancote, West Sussex.
Terrys Cross House is a charity providing care primarily for the Church of England community.
A spokeswoman for the Diocese of Chichester told the West Sussex County Times a senior member of its care team had been immediately suspended pending an investigation into the allegations.
“We take safeguarding very seriously and emphasise that the safety, care and protection of our residents is paramount,” the spokeswoman added.
Sussex Police said it had been made aware of the safeguarding allegation and was liaising with the council to establish the circumstances.
Debbie Ivanova, deputy chief inspector of adult social care with the Care Quality Commission, said: “This incident is currently being dealt with by local safeguarding team and has been referred to the local police.
“It would be inappropriate for CQC to comment further until these agencies have completed their investigations.”
Terrys Cross House is registered to provide personal care for up to 12 people. The service was rated Requires Improvement by the CQC following its last inspection in September 2017.
