(AP) – Federal authorities have seized more than $1.76 million plus other property from northeastern Kansas doctor under investigation for allegedly selling prescriptions for controlled substances.

The U.S. Attorney’s Office filed a civil lawsuit Friday seeking forfeiture of the money plus seven vehicles, eight guns, a house in Parkville, Mo., and a commercial building in Shawnee, Kan.

The Drug Enforcement Agency says in an affidavit that it has been investigating Dr. James R. Webb Jr., of Lenexa, since 2010. Webb has not been criminally charged.

Agents raided his Lenexa medical office, Sports Medicine Consultants, last month. About $1.6 million in cash was also seized from a safe at his parent’s home. DEA says the cash included bills used in an undercover buy.

Webb’s phones were disconnected and a message left at a relative’s house was not immediately returned.
