(CAPITOL CITY NOW) – Illinois State Police seized more than $40 million worth of cocaine during a traffic stop on Interstate 80 east of the Quad Cities on Friday. Vanshpreet Singh, 27, and Manpreet Singh, 36, both from Ontario, Canada, were arrested and charged with multiple felonies, including cocaine trafficking and possession with intent to deliver.

According to ISP, the discovery came after a trooper stopped a semi-trailer for a routine commercial vehicle inspection. Suspicious behavior led to a search of the truck, revealing 1,146 pounds of cocaine hidden inside.

The suspects are being held in the Henry County Jail pending a pre-trial release hearing. The Drug Enforcement Administration’s Chicago Field Division assisted in the investigation. Authorities have not provided additional details at this time.
