PORT JEFFERSON, NY – A 30-year-old man was arrested after he threw a massive party at his $1 million Long Island home, Suffolk Police said.

Michael Malguarnera is charged with violating the county's social host law because officers observed underage drinking at the party, which was packed with about 400 people when police arrived at 1 Crystal Brook Hollow Road in Port Jefferson at about 12:45 a.m. Saturday.



Malguarnera was transported to the Sixth Precinct where he was released on bail. Malguarnera is scheduled to be arraigned at First District Court in Central Islip on Saturday.
