Three people were arrested when police discovered a weapons cache in a vehicle headed to New York City during a search at the Holland Tuel on Tuesday, officials confirmed to Fox News.

Port Authority Police Department Superintendent Michael A. Fedorko said that 50-year-old John Cramsey, 52-year-old Dean Smith and a 29-year-old woman were taken into custody after they were stopped around 7:40 a.m. in Jersey City, N.J.

Officials found multiple weapons -- some loaded -- including rifles and handguns in their vehicle, described by a law enforcement source as a "jacked up SUV."

The vehicle, a Dodge truck, also bore the name Higher Ground Tactical, an indoor shooting range and gun dealership in Upper Milford Township, Pa., WNBC-TV reported.

Ballistic vests and a camouflage helmet were also found in the vehicle, official told WNBC.

A spokeswoman for the Federal Bureau of Investigation, Kelly Langmesser, told Reuters that counter-terrorism agents weren't involved and the case didn't have a "terrorism nexus."

"If it's not terrorism, it's criminal," a source told Fox News.

The trio, from Pesylvania, initially was stopped by Port Authority Police at a toll plaza for a cracked windshield, authorities said. An officer saw the weapons in plain view on the passenger side of the vehicle.

Drugs were also recovered from the vehicle, which has been cleared from the scene but is still being processed for evidence.

The suspects' final destination was unclear. The Holland Tuel's New York side is located in Lower Manhattan.
