Sergeant Matt Ratana was fatally shot in Croydon last year The Metropolitan Police has welcomed seven newborn puppies in memory of a police officer killed in the line of duty in Croydon. Sergeant Matt Ratana, 54, was fatally shot at Croydon Custody Centre in the early hours of September 25 as he prepared to search a handcuffed suspect. Commissioner Cressida Dick has visited the Met’s Dog Training Establishment at Keston to meet the “Ratana litter” alongside Sergeant Ratana’s partner Su Bushby, who chose their names in tribute to him. The German Shepherd puppies have now been allocated to handlers in order to start a 12-month training course to become fully licensed police dogs.
