An alleged drug-dealing dad from Long Island was arrested after police say he used his 13-year-old daughter to help him sell cocaine in Nassau County.

Julio Enmanuel Pena, 39, was busted Monday at his Freeport home and slapped with a slew of charges over the revolting accusations, according to Nassau County police.

The accused lowlife coordinated a cocaine sale with a buyer and had his teenager “complete the transaction,” in a May 26 hometown deal, according to cops and court documents.

He’s accused of sending his daughter to deliver the drugs and bring him back the cash.

Cops executing a search warrant for Pena’s house found 13 bags of cocaine while the suspect was sleeping, according to a criminal complaint. 

Pena was reportedly sleeping at the time of the raid. 

The cellphone used in the drug deal was also found at the residence, prosecutors said. Pena was charged with three counts of criminal possession of a controlled substance, two counts of criminal sale of a controlled substance, conspiracy in the third degree, use of a child to commit a controlled substance offense and endangering the welfare of a child.
