In Gilchrist v Chief Constable of Greater Manchester Police [2019] EWHC 1233, the High Court considered officers’ use of force in the context of use of CS gas and a taser repeatedly upon a man who was autistic and mentally distressed and found that its continued use became unlawful. Whereas the initial use of CS gas and Taser were justified, once the police learned of the male’s vulnerability as an autistic man and noted that his behaviour was defensive rather than aggressive, a more cautious approach should have been adopted.
