The security chief of a Massey Energy Co. subsidiary has been charged with obstructing the investigation of a 2010 explosion that killed 29 miners at the company's Upper Big Branch Mine in southern West Virginia.
The U.S. Attorney's Office in Charleston announced the arrest of 60-year-old Hughie Elbert Stover Monday.
Prosecutors say Stover is accused of lying to investigators. A federal indictment also charges he ordered the disposal of thousands of security documents.
A message left at Stover's home was not immediately returned.
Massey says the company alerted prosecutors when it learned about the documents and acted to recover them and turn them over to the government.
It was the deadliest blast at a U.S. coal mine since 1970.
