Have You Seen Them?

Police investigating Thursday's attempted bombings on the London transit system have released images of four men caught on closed-circuit television at the incident sites around the time the attacks were attempted. The first CCTV image released by police Friday showed a young man in a dark top with 'New York' written on it apparently fleeing the Oval station in south London where a bomb was left on a train. The second image showed a middle-aged man with a moustache wearing a gray T-shirt with a palm tree on it standing on the top deck of the number 26 bus in Hackney, east London. The third image shows a man leaving Warren Street Underground station in central London at about 12:39 p.m. on Thursday. He was wearing dark clothes. The fourth image showed a man at Westbourne Park Underground at 12:21 p.m. He later traveled west on the Hammersmith and City line to Shepherds Bush underground where he ran off. He was wearing a dark shirt and trousers, and was later wearing a white vest. If you believe you have seen these men, or believe you know who or where they are, do not approach them but contact the Metropolitan Police instead.
