Police in Passaic County say that they broke up a party held in an abandoned office building.

Wayne police say that state police tipped them off to the party which was promoted across social media. Police say that hundreds of people were set to attend this party, but that it was broken up before the crowd became too large.

Police say that they plan to charge 50 people who are accused of breaking into the empty office space in the Willowbrook area Saturday night. The doors to the building were apparently forced open and parts of the building were vandalized.

Police say that they also arrested a 20-year-old man who was wanted for robbery.

This was one of three pop-up parties that police thwarted this past weekend. Police in Union Beach say they broke a party up in their town and gave out 15 summonses. They blame a 17-year-old for trying to get the party started.

And police in Roselle claimed to have stopped a pool party at a home in their town. The details of the party were not immediately known, but police say the homeowner did not grasp the magnitude of the planned event, after telling a friend he could use the pool.

Communities up and down the state have been on edge this summer because of several large parties that have broken out. A large one in Long Branch saw 5,000 attendees. Several fights broke out and 15 people were arrested.

Three more pop-up parties were promoted this weekend at the Shore — another in Long Branch, as well as new ones in Asbury Park and Point Pleasant Beach. But those parties did not seem to manifest.
