Police – Negligence. The claimant, aged 59, who had autistic spectrum disorder and bi-polar disorder, had established (to the extent specified in the judgment) liability against the defendant Chief Constable of Greater Manchester Police for trespass to the person and in negligence. The Queen's Bench Division so ruled, concerning an incident in which police officers had used CS gas and a taser, and had physically restrained the claimant outside his flat, after he had suffered an episode of acute behavioural disorder.
