Police issue a fresh warning about the ‘killer clown’ craze as video emerged of one trying to scare a late-night reveller – armed with a HAMMER. Officers warned they were not seeing the funny side after responding to SIX alerts in the space of one evening in a single county. In Plymouth, Devon student George Birkbeck, 22, bravely faced down one of the sinister pranksters who was wielding a hammer. He found himself confronted by the clown – in full costume – around 10pm on Friday and shared the encounter on Facebook. George said the clown refused to move out of his way so he chased him off with a beer bottle out of a crate he had just bought from Tesco.
