A federal complaint says a New York cardiologist may have been illegally prescribing oxycodone and other painkillers for six years.
He wrote prescriptions even after his license was suspended, the complaint says.
The doctor, Rohan Wijetilaka of Manhattan, was arrested Wednesday night. His practice in Yonkers was raided Thursday by federal agents.
The doctor was brought to federal court in White Plains on a charge of distributing a controlled substance. He was released on a $200,000 bond and is due back in court Aug. 22
A message left for his lawyer, William Wood, was not immediately returned.
The complaint says pharmacists have been complaining to police since 2006 about the frequency of the doctor's prescriptions for often-abused painkillers.
It says his state license was suspended last month.
