The female officer suffered potentially life-changing injuries after being stabbed in the arm in Leicester Square. A male officer, who suffered multiple stab wounds, remains under medical observation, the Met said. One police officer involved in the man’s arrest suffered a minor hand injury, while another suffered damage to his protective vest from the knife, which was found at the scene. A 24-year-old man was arrested on suspicion of causing grievous bodily harm and assaulting an emergency worker. He was taken to hospital for treatment of minor injuries before being taken into custody. An investigation into the incident is ongoing and the Metropolitan Police have appealed for witnesses to come forward. Met commissioner Sir Mark Rowley said the officer had questioned the suspect on suspicion of having a knife. He stabbed through a vein in her arm, causing massive blood loss as the suspect tried to escape. A male officer caught up to him but was stabbed three times in the neck and once in the chest. DCS Owain Richards said: “The actions of these two officers, and their colleagues, exemplify the core value of courage that runs at the core of the Metropolitan Police and they will be given all the support they need as they begin their recovery from this terrifying incident.” Anyone who was in the area and witnessed this incident, or who may have captured events on camera or mobile phone, should contact police on 020 8785 8244.
