Hundreds of police officers have paid their respects at a service for Metropolitan Police Sergeant Matt Ratana - who was shot dead on duty in Croydon last year.

A full force funeral couldn't go ahead because of Covid.

Met commissioner Dame Cressida Dick remembered Sergeant Ratana as a "fantastic police officer."

Around 200 officers in full uniform were part of a procession which took in Birdcage Walk in London.
