Japanese police have found a number of severed hands and other body parts in Tokyo Bay.

Investigators believe the Yakuza, or Japanese mafia, could be behind the killings.

A man was fishing in Tokyo Bay off Yokohama when he reeled in a man's head and part of a leg.

Police divers later found more body parts, including several severed hands.

Fingerprints taken from one of the hands match those of a prominent Yakuza member, heightening police suspicions that they are dealing with a gangland slaying involving at least two victims.

The Yakuza have at least 80,000 members in Japan, and control organised crime from prostitution to drugs and extortion.
