The 50-year-old Butler was taken into custody Monday after a grand jury indicted him last week. He’s expected to be released from jail on $1 million bail later Friday.

Butler is accused of selling the drugs confiscated by the Central Contra Costa Narcotics Enforcement Team. Norman Wielsch, the former head of the team, also was indicted in the scheme.
