A spokesperson for Greater Manchester Mental Health NHS Foundation Trust said:
“We are taking the allegations raised by Panorama very seriously since the BBC sent them to us earlier this month. We have put in place immediate actions to protect patient safety, which is our utmost priority.
“Since then, senior doctors at the Trust have undertaken clinical reviews of the patients affected, we have suspended a number of staff pending further investigations and we have also commissioned an independent clinical review of the services provided at the Edenfield Centre.
“We are working closely with local and national partners including NHS England, the Care Quality Commission and Greater Manchester Police to ensure the safety of these services. We will co-operate fully with all investigations.
“We owe it to our patients, their families and carers, the public and our staff that these allegations are fully investigated to ensure we provide the best care, every day, for all the communities we serve.”
