Nassau police on Monday arrested a mother and son they said tried to buy Oxycodone pills with forged prescriptions two years ago.

Detectives had been unable to locate the two but found Michael Campo, 36, of 8803 Pontiac St., Bellerose, when he appeared Monday morning at Brooklyn Criminal Court on a separate drug possession charge.

Detectives charged him with possession of a forged instrument and identity theft. Later that day they found Doreen Campo, 54, of 7227 66th St. in Glendale, Queens, in Manhattan and charged her with possession of a forged instrument.

It was not immediately clear how police located the mother.

Police said Michael Campo tried to use a forged prescription and a male patient's name to get 120 Oxycodone pills at a Walgreens Pharmacy in Franklin Square in 2011.

On three occasions that year, his mother tried to use forged prescriptions for Oxycodone at CVS pharmacies in Farmingdale and West Hempstead, police said.

Both are scheduled to be arraigned Tuesday at First District Court, Hempstead.
