Police in New York City say they have made one arrest related to a crew of thieves that allegedly were involved in at least 18 robberies.
The New York Police Department released a video showing a person in a black shirt, ski mask, and white shoes approaching a jewelry store on Sunday and repeatedly smashing a sledgehammer into the window.
Once the window is broken, another person approaches and assists in stealing the jewelry and putting it into a bag before someone inside the store appears to close down the gate.
An employee at MNP Jewelers was working when the incident happened and told FOX 5 that no one was harmed, and it could have been worse.
"All of a sudden, we heard the boom and I looked at the window," she said. "He could've gotten in here and harmed us but thankfully nothing else happened."
The individuals stole $20,000 worth of jewelry before fleeing in a black BMW 5-series four-door sedan, according to police.
Another jewelry store robbery happened on Monday involving six men using sledgehammers and a pickaxe, smashing the front window of the store and sealing over $180,000 worth of jewelry, according to police.
The men used two vehicles to escape and one of them is a BMW sedan that is similar to the one used in Sunday's robbery.
The group of thieves has allegedly stolen almost $250,000 worth of jewelry, according to police.
