A man has been arrested on suspicion of the murder of a police officer who was shot dead at a Croydon custody centre.

54-year-old Sgt Matiu Ratana was shot in the chest as the suspect was handcuffed on 25 September.

The suspect, 23-year-old Louis De Zoysa, also suffered a gunshot wound and was taken to hospital in a critical condition.

The Met police have said he remains in hospital with “life-changing injuries” as they consult with doctors before interviewing him.
