Al Sharpton was a secret FBI snitch whose recorded conversations with top mobsters helped take down members of the Genovese crime family, a bombshell report claims.

While it was known that Sharpton worked with the FBI in the early 1980s, thesmokinggun.com — citing new documents and extensive interviews with investigators — spelled out new details that for the first time exposed his interactions with four of the five New York City crime families.

The report released Monday said investigators from the FBI and NYPD equipped Sharpton — known as “CI (confidential informant) 7″ — with a bugged Hartmann briefcase into which unsuspecting mobsters spilled their secrets.

Dirt provided by Sharpton helped the feds secure court orders to wire two Genovese family social clubs, including former boss Vincent “The Chin” Gigante’s headquarters, three cars used by the mob and more than three dozen phone lines, including Gigante’s, the report said.

Sharpton worked directly with the FBI/NYPD Organized Crime Task Force, according to the report.

The feds worked hard to shield Sharpton’s identity because the undercover work put his life at risk, the report said.

Sharpton was known to have crossed paths with underworld figures through his work in the music industry and boxing world, including with his mentor James Brown. He also had an association with boxing promoter Don King.

Sharpton, in a Post interview, did not deny that he cooperated with the FBI. But he said the report greatly exaggerated his role.

“It’s crazy. If I provided all the information they claimed I provided, I should be given a ticker-tape parade,” Sharpton said.

He insisted he did not own a briefcase with a listening device.

There’s a dispute about how Sharpton became an FBI informant.

The report said Sharpton was recorded in a meeting that involved an undercover FBI drug sting. While Sharpton did not explicitly offer to arrange a drug deal, the feds had enough to frighten the fiery activist into becoming an informant, the report said.

But Sharpton offered a different account.

He said it was he who contacted the feds after a mobster threatened him while he was acting as a concert promoter.

Later this week, Sharpton will be hosting a meeting of his National Action Network in New York at which President Obama is the featured speaker.
