Russian police are hunting a "werewolf boy" - who snarls and bites - after he escaped from a Moscow clinic just a day after being rescued from the wild.
Doctors expressed shock saying he was found living with a pack of wolves in a remote forest in the Kaluga region of central Russia.
"He's clearly dangerous to other people," said a police spokesman yesterday.
"He's got typical wolf-like habits and behaviour.
"He has very strong and sharp teeth, which could really endanger someone if he bites."
The boy looks about ten - but after tests conducted by Moscow medics, they believe he maybe much older.
