A "toxic staff culture" exists in an NHS mental heath unit, it is claimed. It is also alleged that patients at the Edenfield Centre in Prestwich, Bury, were abused.
As reported in the Manchester Evening News police have started an investigation into the allegations and staff have been suspended. The claims involve 40 patients and 25 staff.
A letter issued by Greater Manchester Mental Health Trust, which runs the unit, says the claims stem from "secret filming" conducted by Panorama between March and June this year. It adds: "The BBC has not allowed us to view the contents of the programme in advance of broadcast."
