Police in Hackettstown say that catalytic converters were stolen off of nearly 20 Amazon trucks parked in a secluded area of town.

The thefts happened late Saturday night off Willow Grove Street. Police say 18 trucks were hit. It is an estimated $20,000 worth of parts.

Thieves have been targeting catalytic converters on vehicles across the state and country over the last few months.

“First time we had an incident of this magnitude with that many catalytic converters. We had a few stolen in December of last year, but nothing of this magnitude,” says Hackettstown Police Lt. Darren Tynan. “It’s a stateside and countrywide thing that people are stealing these [auto parts.]”

Anyone who might have information about the thefts is asked to contact Hackettstown police.
