New York City sheriffs busted an illegal bottle club in Manhattan packed with more than 120 revelers, officials said.

Authorities conducting surveillance at a residential address on Harrison St. near Hudson St. in Tribeca around 11 p.m. Friday saw about 40 people filing into the building.

When deputies gained entrance, they found about 120 unmasked revelers drinking and smoking weed, authorities said.

Among the partygoers was a 17-year-old boy who officials say was “visibly intoxicated” and took a tumble down a flight of stairs.

Medics took the teen to New York-Presbyterian Hospital Lower Manhattan, where deputies stayed with him until his parents picked him up.

Deputies arrested the party host, bartender, two disk jockeys and a man working the party who was carrying 24 individually wrapped 3.5 gram baggies of marijuana, officials said.

Party host Kurt David, 30, of Roslyn, L.I., was charged with unlawfully dealing with children and selling alcohol to a person under the age of 21. He was also charged with violating emergency orders and failure to protect health and safety, a charge the sheriffs say carries a possible $15,000 fine.

Disc jockeys Alberto Mammarella, 32, of Manhattan, and Kazutoshi Sakuma, 45, of Brooklyn, were both charged with violating emergency orders and failure to protect health and safety, which could bring each of them a $1,000 fine.

Bartender Samira Said, 24, of Queens was charged with violating emergency orders.

Nicolas Mora, 29, of Brooklyn, identified as a worker at the party, was charged with unlawful possession of marijuana and violating emergency orders.

Authorities said this is the second time in under a month sheriff deputies were called to the address to bust up an illegal party.
