SAN LEANDRO, Calif. (AP) – Law enforcement agents who raided a sprawling warehouse near Oakland International Airport failed to find the weapons they were looking for, including rocket launchers, officials said Saturday. The owner of the building said he suspects someone reported the weapons as a prank.
After obtaining a warrant to search for rocket launchers and other military weaponry, more than 200 officers from federal, state and local agencies raided the complex early Friday morning, federal officials said.
The search of the warehouse was completed by Friday night. Officers seized some documents but found no weapons or explosives, said Marti McKee, a spokeswoman for the Bureau of Alcohol, Tobacco, Firearms and Explosives.
