BECKLEY, W.Va. (AP) -- A judge has revoked the $10,000 bond of a former Massey Energy executive cooperating in the investigation of the Upper Big Branch mine disaster.
Prosecutors, meanwhile, say they'll ask another judge to immediately detain David Hughart when he's sentenced later Tuesday on conspiracy charges.
Magistrate Clarke VanDervort revoked Hughart's bond following his arrest last week on drug charges.
Assistant U.S. Attorney Steve Ruby said Beckley police stopped Hughart because he was driving erratically.
Hughart faces up to six years in prison when he appears before U.S. District Judge Irene Berger.
He admitted giving miners at Massey subsidiary White Buck Coal Co. illegal advance warning about surprise inspections.
Hughart never worked at Upper Big Branch, where 29 miners died in 2010. But he has implicated former Massey officials in the scheme.
