Two men were arrested and a semi-truck was seized on Saturday after police discovered the vehicle's driver's side fuel tank was holding $90.8 million worth of liquid meth.

Raul Arreola, 48, of California, and Aquileo Pineda, 49, of Georgia, were booked at the Harnett County Detention Center in Lillington, North Carolina, on three counts of trafficking methamphetamine, WTVD reported.

Investigators found 120 gallons of liquid meth in the truck's tank, the news outlet reported, citing Harnett County Sheriff Wayne Coats. That amount reportedly equates to 454 kilograms of crystal meth.

Both men were being held at the county jail on a $3 million bond, sheriff's office records showed.

An immigration detainer, according to WTVD, was issued for Pineda and immigration officials with ICE were trying to determine Arreola's current immigration status.
