Face-down restraint ban considered

Mental health services in England could be banned from using face-down restraint and many are training their staff to resolve issues without physical intervention.
Research by the charity Mind says many mental health trusts no longer use face-down restraint because it is considered dangerous and traumatic, but some trusts still use the procedure two or three times a day.
Sheffield Mental Health Trust's medical director, Professor Tim Kendall, is currently reviewing official guidance on restraint. He gave BBC News a demonstration of the technique.
