As if his taunting Al Capone and ‘Untouchable’ tattoos weren’t enough, a mobster wannabe had a vanity license plate that read ‘DaBadGuy,’ authorities said after busting the alleged heroin dealer Monday.

Bryan Koppelman, 32, of Selden and seven others were arrested and charged after authorities seized 19,000 glassine envelopes of heroin ready for street sale, officials said.

The ring distributed large quantities of the drug throughout towns on eastern Long Island, said Suffolk County DA Thomas Spota.

Suffolk officials displayed photos of the attention-grabbing Koppelman’s tattoo-adorned back and flashy license plate to reporters at a morning press conference at the district attorney’s headquarters in Hauppauge.

His tattoos included a portrait of the late Chicago-based mobster Capone and the word “Untouchable’’ scrawled across his back.

The drug gang’s alleged ringleader, Richard Bruno Jr., 26, of Holbrook, LI, and his 59-year-old father were also among those busted.

Bruno Sr. was caught storing heroin in the attic of his single-story Long Island home, authorities said. Investigators said they also uncovered a large sum of cash at his residence.

The suspects were charged after the joint investigation headed by the District Attorney’s Heroin Task Force and New York State Police.

Besides cocaine and heroin, task-force investigators executing search warrants recovered crystal methamphetamine, anabolic steroids, cash and a trove of assault-style semiautomatic weapons including a defaced handgun.

The drugs were transported to Long Island from Brooklyn.

The operation’s alleged supplier, Jonathon Rincon, 26, of Sheepshead Bay, was held in lieu of $1.5 million bail, as were Bruno Jr. and Koppelman.
