Ex-Mob Boss 'Junior' Gotti Stabbed But Not Cooperating With Cops

John A. "Junior" Gotti is the former acting boss of his father's Gambino family.

Nov. 11, 2013 — -- Detectives are investigating an incident in which John A. "Junior" Gotti, the son of the late "Dapper Don" John Gotti, was apparently stabbed Sunday night in the parking lot of a CVS drug store in Syosset, N.Y., authorities said today.

"The Nassau County District Attorney's can confirm they are investigating, in conjunction with Nassau County Police, an alleged stabbing of John 'Junior' Gotti," a spokesman for the district attorney's office told ABC News.

Gotti, 49, reported he was breaking up a fight between strangers, but so far cops have nothing to back that up, according to an official briefed on the incident. Police were notified of the incident about 9:45 p.m. Sunday, after Gotti drove himself to Syosset Hospital.

Gotti, the former acting boss of his father's Gambino crime family, was transferred to North Shore University Hospital from Syosset Hospital. Gotti has been released from North Shore hospital.

So far, Gotti has declined to cooperate with investigators or assist in the investigation, police said.

"He's being very uncooperative," an official told ABC News. "He says these guys were fighting and he jumps in and is this big savior and he gets stabbed in the stomach."

Gotti sustained a stomach injury, but cops don't know how severe it was.

Detectives are collecting security camera video from the scene.
