John Gotti

John Gotti Jr.’s 23-year-old namesake grandson, John Gotti, was arrested for dealing drugs out of the mob figure’s iconic Howard Beach, NY home.

The feds raided Gotti Jr.’s immaculate home in the upper middle class neighborhood in Queens on Thursday.

It was the first time law enforcement officers had ever executed a search warrant at the House of Gotti.

The late mob boss, who died in 2002, kept his criminal activities separate from his home life to protect his family, friends say.

Federal agents ransacked the house after undercover officers bought $46,000 worth of Oxycodone pills from the grandson.

Agents found 500 Oxycodone pills and $40,000 in cash inside the home.

“They destroyed the house,” said Gerard Marrone, the lawyer representing John Gotti, whose father is Gotti Jr.’s mob son, Peter Gotti.

Retired FBI supervisor Phil Scala said the grandson violated John Gotti Jr.’s one sacred rule.

“If John was still alive he would be spewing every pejorative he could, knowing that somebody did something so stupid to besmirch his home and his family,” Scala told the Daily News.

“He’s lucky his grandfather is not alive,” said family friend Lewis Kasman. “John Sr. would have killed the kid himself.”

Kasman added: “No wiseguy was allowed in that house and the only non-blood family member permitted inside was me. That was his palace, so to speak. This is a desecration of everything that John stood for in terms of the family house being sacred.”

The feds wiretapped young Gotti’s Infiniti sedan to build a case against him. Wiretaps picked up Gotti saying he sold more than 4,200 pills a month and pulled in $100,000 a month.

The feds arrested 7 accomplices in the drug bust, including Shaine Hack, 37, who was holding $200,000 in drug proceeds for young Gotti in his Howard Beach home.

The bedroom of Gotti Jr.’s son Frankie Gotti, who died at age 12 in a tragic car accident in 1980, was maintained as a shrine in the house, Kasman said.

John Favara, the man who accidentally hit and killed Frankie who was riding his minibike in the street, attempted to apologize to Gotti’s grieving wife, Victoria Gotti, but she attacked him with a baseball bat.

Several months later, witnesses saw several men throw Favara into the back of a van. He was never seen or heard from again.
