Authorities have arrested two and seized millions of dollars’ worth of crystal meth after discovering it hidden in a semi-truck near Fayetteville.

The Harnett County Sheriff’s Office was already deep into an investigation about the trafficking and transportation of methamphetamine in the area when they stumbled upon this find. Officials discovered the 2009 Peterbilt truck in Linden near the 100 block of Will Lucas Road, and they decided to conduct a search. Police searching the truck revealed a strange substance stored within the driver’s side fuel tank. Lab testing confirmed the substance was liquid methamphetamine, and there was at least 120 gallons worth of the drug stashed away.

On the street, this liquid methamphetamine would have been converted into the more common form of crystal methamphetamine. After the conversion, the two suspects would have made over 454 kilograms of meth. The street value of such an amount was estimated to be around $90.8 million.

The truck was being driven by 49-year-old Raul Arreola and 48-year-old Aquileo Perez Pineda. The two individuals were promptly arrested and transported to the Harnett County Detention Center. Each suspect will face three counts of trafficking the dangerous drug methamphetamine. Officials confirmed that both suspects are being held under a $3 million bond.

The U.S. Immigration Customs and Enforcement Agency was contacted to confirm the status of the two suspects. An immigration detainer has been issued for one suspect, Aquileo Perez Pineda. The agency is still investigating the immigration status of the second suspect, Raul Arreola.
