Authorities say Dr. Leonard Stambler of Baldwin Harbor was writing large numbers of prescriptions for Oxycodone to patients who were then believed to be reselling or abusing the medication.

Federal officials say he did not have an office and instead would drive around and deliver the pills directly to patients.

Authorities also said agents witnessed Stambler illegally exchanging Oxycodone pills more than 20 times between March and November of this year.

If convicted, the 60-year-old faces up to ten years in prison.

This latest arrest comes on the heels of another doctor being arrested last week for allegedly selling prescription drugs.

The Manhattan prosecutor’s office said Dr. Stan Xuhui Li had been supplying pills to Medford pharmacy shooter David Laffer.

Investigators think Li may have also sold prescriptions to nine other people who died of overdoses since January 2009.
