STOCKHOLM -- A pet crocodile kept by a Hell's Angels motorcycle gang member has led police in southern Sweden to an illegal arms hoard. The biker turned on the tap in his apartment in the city of Malmo to put fresh water in the croc's aquarium, but fell asleep before turning it off, the Swedish TT news agency quoted local newspapers as saying on Monday. Neighbors in the apartment building called the police when water began seeping out from under the biker's front door. Police investigating the call found an illegal arms cache inside. The biker, who admitted to possession of the weapons without licence, faces up to a year in prison, Reuters reported.
