(NEW YORK) -- Three people were taken into custody Tuesday after police found several weapons in their car as they headed into the Holland Tunnel en route to New York City.
Police recovered seven guns — including rifles and handguns — as well as four knives, 10 clips of ammunition, body armor and a military-grade helmet.
The number of weapons in the car raised suspicions, and the Joint Terrorism Task Force was called, but two law enforcement officials told ABC News there does not appear to be a link to terrorism.
The reason for the large number of weapons was not immediately clear; one police source said it appeared to be related to heroin.
The three taken into custody told police they are self-styled vigilantes and said they were driving to the city's borough of Queens to rescue a teen girl who recently overdosed and was not in a good situation.
Police stopped the two men and one woman Tuesday morning at the New Jersey toll plaza of the Holland Tunnel — which runs from Jersey City to lower Manhattan — because their car had a cracked windshield, Port Authority Police said.
A Port Authority police officer spotted a gun on a seat in the car, officials said.
Drugs were also allegedly recovered.
All three suspects are being held in Jersey City, police said.
