Authorities have raided a doctor's two offices and home in southwest Ohio, seizing boxes of records in an investigation of possible prescription drug abuse.
The Dayton Daily News reports that 69-year-old Dr. Han M. Yang says authorities are "off-base" in their allegations. He says he has surrendered his license to practice medicine in Ohio and will give up his practice. He also says he will seek an attorney.
Clark County Sheriff Gene Kelly says patients were lined up outside Yang's Dayton office. Authorities say they suspect many people are getting prescription painkillers and other drugs to sell on the street.
Ohio Attorney General Mike DeWine says the state with help from federal investigators will bring full force to bear on doctors who permit misuse of prescription drugs.
