The allegations against Richard J. Delabrer, of Laurel, Md., are part of the wide ranging corruption investigation of Prince George's County Executive Jack Johnson and his wife, County Council Member Leslie Johnson.
Federal authorities say Delabrer was paid by a prominent local liquor store owner to assure the transportation of untaxed alcohol in Maryland and Virginia. He was arrested in November and charged with conspiracy to commit extortion.
In addition, court documents indicate Delabrer also purchased untaxed cigarettes from an undercover agent and then resold them.
Delabrer, who retired in November after more than two decades on the Prince George's County Police force, is scheduled to appear in U.S. District Court in Greenbelt on May 25 for a re-agreement hearing. Details of the agreement have not been made public.
