Met Police launch murder investigation after a police officer was shot dead at a South London custody centre.
The Metropolitan Police say a 23-year-old man was detained at the scene at Croydon Custody Centre.
The officer was shot at 2.15am on Friday by a man who had already been arrested.
Commissioner Cressida Dick said: “This is a truly shocking incident in which one of our colleagues has lost his life in the most tragic circumstances. My heart goes out to his family, direct colleagues and friends.”
“We are currently supporting his family and also have a dedicated team providing support to the officers and those in the custody centre who witnessed the shooting.
“When a colleague dies in the line of duty the shockwaves and sadness reverberates throughout the Met and our communities. Policing is a family, within London and nationally, and we will all deeply mourn our colleague.
“We are in the early stages of the investigation and are still working to establish the circumstances surrounding the incident and we will provide further updates when we have them.”
