Police in Pennsylvania are searching for two truck drivers after authorities say they stole more than $3,000 in diesel fuel from a Wawa gas station last week.

The thefts happened in Hilltown Township on the morning of Jan. 11 at a Wawa on Route 131, police said.

The first theft occurred around 7:45 a.m. when the driver of a white flatbed-style truck illegally accessed the control unit of a diesel fuel pump, according to police. The driver bypassed the pay system and pumped out 342 gallons of diesel fuel before driving away.

About an hour and a half later, a white Ford F-150 pickup truck used the same pump and bypassed the pay system, police said. The driver stole 261 gallons of diesel fuel.
