(KTLA) — One person was arrested after U.S. Customs and Border Patrol Protection agents at a California checkpoint found $60,000 worth of methamphetamine stuffed into child booster seats, according to authorities.

Agents at the Newton Azrak Border Patrol Station in Murrieta stopped a vehicle on the 15 Freeway on Wednesday, June 15.

There were two adults and four children inside the car, officials say.

A Border Patrol K-9 team alerted the agents to the presence of narcotics inside the children’s three booster seats, CBP announced Friday, June 17.

Agents examined the children’s seats and found several packages of a white crystal substance that turned out to be meth, according to CBP officials. 

The agency says the driver was found in possession of 26.9 pounds of methamphetamine, with an estimated street value of $60,000.

The driver was reportedly arrested on suspicion of attempting to smuggle methamphetamine in the booster seats, and the vehicle was seized. 

Meanwhile, the four children and their mother were released, officials say.

“Drug smugglers will use any means necessary to get their poison onto our streets. Nothing is sacred to them, not even family,” CBP Chief Patrol Agent Aaron M. Heitke stated.
