A canine team screening vehicles at the San Ysidro Port of Entry Tuesday alerted officials to inspect the undercarriage of the bus, said Angelica De Cima, a spokeswoman for U.S. Customs and Border Protection.
Officers found 177 packages of marijuana hidden in a compartment built into the gas tank of the bus, which was carrying 22 passengers, U-T San Diego reported Wednesday. The value of the drug was estimated at $350,000, De Cima said.
Police arrested the 37-year-old driver, a Mexican citizen whose name was not reported, and booked the suspect into the Metropolitan Correctional Center.
