The daughter of former U.K. Prime Minister Tony Blair was held at gunpoint by two men while walking her dog in London. Kathryn Blair, 25, was out in central London with her boyfriend on Monday (16Sep13) when two men attempted to rob them. The pair escaped unhurt and nothing was stolen. Police have now launched an investigation, and have linked the men to another attempted robbery earlier in the day. A statement from Scotland Yard says, "The victims were a man and a woman, the suspects were two males." A spokesman for the Blairs adds, "Kathryn was with a group of friends. No one was hurt and nothing was stolen." The incident came just days after Kathryn attended her brother Euan's wedding to Suzanne Ashman in Buckinghamshire, England over the weekend (14-15Sep13).
