http://news.bbc.co.uk/1/hi/england/bristol/8192209.stm A gang brandishing snakes as 'weapons' attacked a 14-year-old boy with a python, forcing the reptile to bite the teenager's hand. Paramedics who attended the scene in Bradley Stoke, South Gloucestershire, were left baffled by the injury and called Bristol Zoo for advice. The boy was pinned against a wall by the gang on Saturday afternoon, before one forced the python to attack. The teenager was taken to Frenchay Hospital for checks. 'Puncture wounds' Police and the RSPCA are now investigating the incident, which took place shortly before 1500 BST . A spokesman for Great Western Ambulance service (GWAS) said: "Ambulance staff consulted Google and Bristol Zoo experts after a teenager was attacked by a group of youths brandishing snakes. "The group was apparently carrying several snakes and forced one of them to bite the boy on the hand, leaving two puncture wounds." Pythons are ambush predators which rely on crushing their prey, and are not venomous. GWAS incident support officer Michael Howells, who was at the scene, said: "Although the patient was suffering breathing difficulties after the attack, this was probably due to panic rather than a reaction to the bite - I would probably be panicky if that happened to me."
