Word to the wise: Always pay your storage fees if you're hiding drugs. And you're a cop.

On Wednesday the San Jose Police Department announced that a 20-year veteran was arrested after authorities found a huge pot stash in his storage locker.

Son Vu, 42, was booked a day prior and charged with two felony counts of marijuana possession for cultivation and sales. His bail was set at $20,000.

Authorities were alerted to the drug stow when employees from Public Storage on Tully Road were clearing through storage lockers from tenants past-due on rent. On Tuesday, they found the sizable cannabis cache—20 pounds of it, by one account—and called the cops.

SJPD summoned its Internal Affairs unit and later found out that Vu rented the storage closet. Vu was booked and placed on paid leave.

"We will not tolerate such conduct—especially criminal conduct—and we will hold those responsible for their actions," SJPD Chief Larry Esquivel said. "We are working closely with the Santa Clara County District Attorney's Office to ensure this investigation is thorough and complete."

Vu is the second San Jose officer arrested this year. Officer Geoffrey Graves, 38, stands accused of raping a woman he dropped off in a motel room after picking her up from a domestic violence call while on duty. Graves pleaded not guilty, but prosecutors added new charges last month, accusing him of assaulting an ex-girlfriend.
