Deputy sheriffs shut down an illegal Halloween party early Sunday that drew more than 500 revelers to a Bronx warehouse.

Authorities charged nearly two dozen organizers with operating without a liquor license and violating the city’s ban on large gatherings.

Partygoers wore costumes, but many were not wearing proper masks, the New York Post reported.

Deputies went into the warehouse on Seabury Avenue about 1:30 a.m. and dispersed the tightly-packed crowd. The venue had a large walk-up bar, food truck and two DJs, the Post reported.

Deputies broke up a similar bash the night before inside a warehouse in the East Williamsburg section of Brooklyn that drew nearly 400 people. Nine organizers were charged in that bust.
