Talk about a low blow.

Accusing his son Michael of talking to the FBI, mobster Frank "Frankie Camp" Campione wrote to him, "You are my son and you came from my balls and you should have known better. You have totally crushed me beyond repair."

The Colombo family soldier also accused his son, who reportedly is not involved in organized crime, of being a "rat" and of cutting him off from seeing his grandchildren.

Prison officials seized the letter as evidence that Campione has not repented for his crimes and is still involved with the mafia.

Campione is awaiting sentencing for shaking down a Long Island gambling club.
