Former Prince George’s County Executive Jack Johnson was indicted Monday on eight federal charges of conspiracy, extortion and bribery as well as tampering with a witness and evidence. Authorities say Johnson took bribes from developers seeking favorable treatment, and he and his wife attempted to cover it up.

The indictment, filed in U.S. District Court in Greenbelt, also says Johnson conspired with 51-year-old Amrik Singh Melhi, who owned a number of liquor stores in Maryland, and others, in accepting bribes.
