A police officer has died after his unmarked motorbike was in collision with a car.
The officer, who was on duty and riding a police motorcycle, was involved in the accident with a silver BMW car outside a Shell petrol station in Swaythling.
The officer, who has not been named, was taken to Southampton General Hospital but was pronounced dead on arrival.
His next of kin and colleagues have been informed.
The driver of the BMW, a 35-year-old man, sustained serious but not life-threatening injuries and was taken to Southampton General Hospital for treatment.
Chief Constable Andy Marsh said: ‘This is an immensely sad day for the constabulary and the force will be deeply affected.
‘We are supporting the officer’s family in every way we can and our thoughts remain very much with them at this time.’
Hampshire Constabulary said the officer was not involved in a pursuit at the time of the collision and was not responding to a 999 call.
Simon Hayes, the police and crime commissioner for Hampshire, said: ‘This is a very sad day for Hampshire Constabulary and a tragic loss of a police officer in the course of his duty.
‘This tragic incident highlights the fact police officers regularly put themselves at risk in performing their duty and in protecting the public.
‘Our thoughts and sympathy go to this family and colleagues at this very difficult time.’
