An accountant at a New York ad firm leaped to his death because he was hallucinating that the mannequins at his Manhattan office were chasing him, it was claimed today. David Caquais, 43, opened at window at Catch NY on the fourth floor of a building in Manhattan's Garment District and jumped out about 9pm on January 2. The New York Post reports that Mr Caquais screamed 'They're after me! They're after me!' as he ran around his office and attempted to kick out windows.
