The Drug Enforcement Administration has arrested two people and deported six others following the bust of an alleged drug ring operating out of a truck stop in Barstow , CA .

The eight employees of Heartland Truck Stop in Barstow were arrested following a three-year investigation into drug trafficking at the business, according to the Victorville Daily Press.

The employees are suspected of selling methamphetamines at the business. Undercover investigators say they bought 20 pounds of meth at the truck stop during the course of their investigation and discovered another pound during the raid.

California Highway Patrol Officer Adam Cortinas told the Daily Press that it’s possible other drugs were being sold out of the stop as well.

Immigration and Naturalization Services, Immigration and Customs Enforcement, the San Bernardino County Sheriff’s Department, the California Highway Patrol, and the Barstow Police Department all assisted in the investigation.

Cortinas told the Daily Press there are still as many as nine more individuals still wanted in connection with the investigation.

Investigators plan to search homes and other locations in Barstow for the other suspects. The truck stop itself is still under investigation and anyone with any information is asked to call the We Tip Headquarters at 1-800-782-7463.
