Police say a dentist and a town worker are tied up in a scheme that saw them sell 7,000 opioid prescriptions.

They say Dr. Jason DiBlasi, of Farmingdale, is accused of selling opioid prescriptions to patients who didn't need them -- and in some cases -- patients he'd never met. Town of Oyster Bay employee Marco Cotto, 52, is also facing charges in the scheme.

The pair have pleaded not guilty to over 100 counts of criminal controlled substance sales.

Both could face up to five years in prison if convicted.
