U.S. Border Patrol agents assigned to the Interstate 8 checkpoint said they seized a large amount of liquid methamphetamine on Monday with an estimated street value of $500,000.
Agents from the Calexico station said they were working the westbound checkpoint when they encountered a suspicious blue sport utility vehicle.
The vehicle was referred to a secondary round of inspections where agents found a suspicious oily substance in the window washer fluid reservoir, located within the engine compartment.
The substance was later determined to be liquid methamphetamine with a value of $505,600.
The Drug Enforcement Administration took custody of the driver, vehicle and narcotics.
No one was injured.
