A police car which mowed down and killed an elderly grandfather on a 999 call-out was racing at an 'unjustifiable speed' given its siren was off, a coroner has ruled. David Ormesher, 79, was hit at 57mph by the Sussex Police patrol vehicle in Edward Street, Brighton, during the early hours of August 25, 2017 as officers responded to an emergency. He was pronounced dead at the scene having suffered multiple injuries, including a serious head injury, and a cardiac arrest. The police car had struck Mr Ormesher about 40 metres from the western-most point of the junction with Upper Rock Gardens in Edward Street at 12.53am.
