U.S. Drug Enforcement Administration agents have arrested a South Florida man suspected of manufacturing and supplying banned performance-enhancing drugs for Major League Baseball players and other athletes.

A DEA complaint unsealed Tuesday charges Paulo Berejuk with conspiracy to distribute testosterone. Berejuk was scheduled to make an initial court appearance later Tuesday. It wasn't immediately clear if he had a lawyer.

A DEA affidavit describes Berejuk as a "black market source" for testosterone to clinics whose customers included MLB players. The affidavit says Berejuk is a chemist who made the substances in his garage.

The arrest is the latest in the recent MLB drug scandal that resulted in 14 player suspensions and felony drug charges against a half-dozen people connected with the clinics, including former Biogenesis of America owner Anthony Bosch.
