Police will no longer be able to hold people who are being detained for mental-health reasons in police cells, under government plans for England and Wales.
Officers can currently use cells as a "place of safety" for up to 24 hours to allow those needing immediate care to be assessed by a doctor.
New legislation will also introduce additional rights for those receiving treatment, in a bid to modernise decades-old mental health laws.
Charities have broadly welcomed the changes, whilst highlighting the need for better funding for mental health.
Health Secretary Wes Streeting said the "outdated" system was in need of changes to bring it "in line with the 21st Century".
