Officers at the Hidalgo bridge arrested a Houston man on Thursday, when they caught him with 163 pounds of liquid methamphetamine, according to federal court records.

William Joe McCallister, 49, of Houston attempted to cross the bridge from Reynosa to Hidalgo on Thursday driving a blue Ford Expedition.

Officers sent McCallister to secondary inspection, where they found 163 pounds of liquid methamphetamine "concealed in an aftermarket compartment within the gas tank," according to the federal criminal complaint against him.

U.S. Customs and Border Protection contacted Homeland Security Investigations, a division of U.S. Immigration and Customs Enforcement, when sent agents to question McCallister.

McCallister said "he knew he was smuggling drugs into the United States," according to the criminal complaint.

McCallister is charged with importing methamphetamine. He is scheduled for a preliminary examination and detention hearing on Tuesday.
