Greater Manchester Police (GMP) is preparing to launch a probe into the care of patients at a mental health unit in Prestwich.
The force is getting ready to investigate alleged mistreatment of patients at the Edenfield Centre, located on the Prestwich Hospital site.
It is understood the action is being taken after the BBC Panorama programme sent an investigative journalist to go undercover in the unit.
The Edenfield Centre provides secure treatment for adults with enduring mental health needs.
A GMP spokesperson said: "We are aware of the allegations and are liaising with partner agencies to safeguard vulnerable individuals and obtain all information required to open an investigation."
In response to the investigation a spokesperson for Greater Manchester Mental Health NHS Foundation Trust said: “We can confirm that BBC Panorama has contacted the trust following research it conducted into the Edenfield Centre.
“We would like to reassure patients, carers, staff and the public that we are taking the matters raised by the BBC very seriously.
“Immediate action has been taken to address the issues raised and to ensure patient safety, which is our utmost priority.
“We are liaising with partner agencies and stakeholders, including Greater Manchester Police.
“We are not able to comment any further on these matters at this stage.”
