Police Sergeant Edmund Frost lived and worked in Halstead before being posted to the opposite end of the county when he joined the force. He worked at various stations in the Romford division before being promoted to sergeant, returning briefly to the rural end of Essex before being posted back to Romford at the start of the Second World War.
Edmund Frost was commended by the Chief Constable for consistent good work in air raids on Romford. In August 1946 Edmund Frost had a long period of sick leave after being kicked by a deserter. He returned to work and was posted to Harlow, but succumbed to a fatal disease which was directly related to the injury on duty he had received.
