A health service regulator is investigating claims of abuse at a care home in Lancashire.
Monitor is looking into whether Calderstones Partnership NHS Foundation Trust breached its licence when a patient was abused while in its care.
The health regulator stepped in after a safe guarding case conference identified shortcomings. Police investigated specific allegations of abuse earlier this year but decided to take no further action.
Monitor will now look into whether the episode may be evidence of wider problems at the trust.
"The fact that this issue was not identified by the Trust may indicate a failure in the way the Trust is working, so we have opened a formal regulatory investigation and also asked the CQC to assess the quality of care provided by the Trust as a priority."We want to make sure that patients are receiving the best possible standards of care, and we will look closely at how the Trust is run to determine whether it has breached the conditions of its licence to provide NHS healthcare services."
The regulator has also written to the Care Quality Commission asking it to undertake an urgent review of standards of care.
No decision has been taken about whether regulatory action is required.
