WOODBRIDGE, N.J. (PIX11) — A group of armed robbers stole from a jewelry store in New Jersey on Friday, police said.

The alleged thieves, who were wearing masks and gloves, followed an employee through the shop’s front door at around 7:45 p.m., according to authorities. The suspects forced the employees to the floor, smashed several glass display cases and took the jewelry inside before fleeing the store in less than two minutes.

Some employees sustained minor injuries, officials said. The total amount of the stolen items is yet to be determined.

Eight robbers were seen on video, but police believe there could also be additional suspects who were in the getaway vehicles.

Local store owners in the area told PIX11 News the thieves clearly knew what they were doing. The jewelry shop doors in the area are all locked and require someone to push a button to let you in. The robbers waited for a person to get buzzed in so they could catch the open door and make their move.

Police asked for help from the public in finding the suspects.

Anyone with information is asked to please contact Woodbridge Police Detective Perry Penna at 732-624-7700.
