BIRMINGHAM, Ala. (AP) — An Alabama doctor has been charged with illegally prescribing controlled substances.

U.S. Attorney Jay E. Town, in a news release, said federal prosecutors in a one-count bill of information charged 60-year-old Steven Bruce Hefter Friday with conspiracy to dispense and distribute Schedule II controlled substances, including oxycodone, methadone and hydrocodone between 2012 and December 2015.

Hefter worked at a pain management clinic in Moody that closed after investigators began looking into the clinic's prescribing practices.

Prosecutors also filed a plea agreement with Hefter that requires him to surrender his medical license, along with his state and federal Drug Enforcement Administration certificates to prescribe controlled substances. He will be prohibited from ever practicing medicine in the United States. A federal judge must accept the terms of the agreement before it's final.
