An Atlanta man has been arraigned on federal charges related to last summer's explosion of an alleged PCP lab set up in a Fairburn home, and a Powder Springs man also named in the indictment is still being sought.

The charges stem from a July 6 fire in a Fairburn neighborhood that burned for almost two days and destroyed a home.

"Further investigation revealed the presence of numerous barrels and canisters of chemicals suggesting the presence of a large, clandestine PCP lab in the residence," said Bob Page, spokesman for United States Attorney Sally Quillian Yates.

On Jan. 14, a federal grand jury indicted Adrian Banks, 39, of Atlanta, and Coleman Warnock, 41, of Powder Springs, charging them with one count of conspiracy to manufacture PCP, four counts related to the manufacture of at least one kilogram of PCP and one count of creating a substantial risk of harm to human life while attempting to manufacture PCP.

Banks was arrested on Jan. 16, and was arraigned on the charges this week.

Warnock remains a fugitive, according to Page.
