The son of ex-"Real Housewives of Orange County" star Lauri Peterson is allegedly dealing drugs ... at least according to prosecutors who claim he was angling to sell fentanyl.
According to new legal docs, obtained by TMZ, Josh Waringis facing criminal charges from an arrest back in January, including felony possession and the sale of fentanyl, plus a misdemeanor charge of methamphetamine possession.
Orange County Sheriff's Dept. sources tell TMZ ... a deputy saw Josh in the passenger seat of a car, recognizing him from a prior drug arrest. The deputy was aware Josh was on parole for an assault, which meant the cop could conduct a random search, which he did, and allegedly found drugs right on Josh's lap.
Our sources say the deputy saw Josh brush the drugs onto the car's floorboard ... drugs later identified as fentanyl and meth. We're told Josh was arrested on the spot and taken to jail. As for why he was charged with the sale of fentanyl ... it's because of the amount found.
As you know, Josh has a history of legal troubles ... he was arrested back in 2016 when he was accused of shooting a man outside a sober living home. Josh spent 4 years in jail, where he was once ambushed and assaulted by another inmate who was wielding razors wrapped in towels -- the attack was caught on video. He was later released on parole.
