Metropolitan Police must change way it deals with mental illness, panel says They made 28 recommendations, including changes to the systems, policy, procedures, training and attitude of officers and better co-operation with outside agencies. Up to a quarter of the Met's calls - 600,000 a year - are linked to mental health issues, and unless the problems are understood "people can, do, and will continue to lose their lives," the panel said. Commissioner Sir Bernard Hogan-Howe, who set up the review, said he was "grateful" for the report and broadly accepted the recommendations.
