FP-AMERICANS already rocked by the devastating car bombing in Oklahoma City awoke on the 22nd to a new nightmare scenario a reported plot to flood Disneyland with lethal nerve gas. The Baltimore Sun reported that US authorities thwarted plans for an attack on the California amusement park by members of a Japanese doomsday sect liked to the gassing of the Tokyo metro last month. Disneyland issued a statement in Los Angeles saying it had received a threat before the Easter weekend and notified federal authorities, who determined it was a hoax. A criminal investigation is being conducted by the FBI in an effort to identify and prosecute whoever was responsible for carrying out the prank.
