Interpol has issued an arrest warrant for Whale Wars reality star Paul Watson after the conservationist skipped bail in Germany. He vanished as Costa Rica was attempting to extradite him on charges of endangering a fishing vessel off Guatemala in 2002, CNN reports. Watson, known for boat maneuvers interfering with whale hunts, is charged with damaging the Guatemalan boat as he attempted to protect sharks who were being killed for their fins. A spokesmen for the Sea Shepherd Conservation Society said the organization's boat, the Ocean Warrior, used water cannons on the fishing vessel, but “there were no injuries and no physical damage." The confrontation was part of a 2007 documentary, Sharkwater. Sea Shepherd is refusing to divulge Watson's whereabouts. (More Paul Watson stories.)
