An armed robbery at a jewelry store in Passaic may be linked to a burglary at a Montville gun shop on Friday.

Passaic Mayor Hector Lora says that one woman and four men robbed the A&C Jewelry Exchange on Jefferson Street in Passaic around 7 p.m. They made it out with an unknown amount of jewelry and are being tracked by federal agents. They are believed to be involved in other robberies and burglaries.

Lora told News 12 New Jersey he was thankful no one was hurt.

News 12 previously reported about a burglary at FSS Armory in the Pinebrook section of Montville that happened around 1:30 a.m. on Friday. Guns and ammunition were stolen.

“When guns are out in the street it is always a concern for us,” says Montville Police Chief Andrew Caggiano. “But as far as the residence of Montville, I don’t have a concern that they are here. We will continue our investigation and see where that leads us.”

Caggiano says that he is aware of the robbery in Passaic and is looking into the possibility of a connection.

A description of the suspects involved in either crime has not yet been provided.
