Assault raps against Mafia scion John Gotti Jr.’s wife and daughter were dropped Tuesday in a case involving a wild brawl at a youth basketball game on Long Island, officials said. Kimberly Gotti, 55, and Gianna Gotti, 23 — the daughter-in-law and granddaughter of infamous late Mafioso John Gotti Sr.

— were accused of attacking a woman at a Feb. 8 basketball game at Locust Valley High School when the woman shouted insults at Kimberly’s son Joe, who was playing the visiting team from Oyster Bay High School. The mother-daughter duo allegedly slugged the woman and ripped off her wig while calling the other team’s players “f—–ts and p—ies.

” The misdemeanor third-degree assault charges against the Gotti women were tossed Tuesday “on procedural grounds,” according to a rep for the Nassau County District Attorney’s Office. The office did not elaborate on what the procedural grounds were. But Gotti lawyer Gerard Marrone said his clients refused to take previous plea offers from prosecutors because of witness credibility issues, including involving the alleged victim’s unrelated criminal history, and because the DA’s office failed to turn over evidence on time.

“When we really looked into it, we realized that the complaining witness in the case had a substantial criminal record and was charged with a felony,” the lawyer said. “The DA’s office did not tell us that, and then they did not give us discovery in a proper, timely fashion.” Marrone said.
