A friend of the man accused of gunning down nine parishioners at a Charleston church is charged with lying to federal authorities and concealing information during their investigation, and he was scheduled for his first court appearance Friday.
 
Court documents dated Tuesday and unsealed Friday say that Joey Meek, 21, told an FBI agent that he did not know specifics about Dylann Roof's plan to shoot the churchgoers during Bible study, but the FBI says that was a lie.

Authorities notified Meek last month that he was under investigation. He was arrested Thursday. It wasn't clear whether he had an attorney to contact for comment on the case, but his girlfriend has said he is innocent. Meek was expected to appear in court for arraignment at 11 a.m. Friday.

Meek has said Roof stayed with him in before the shootings. Meek previously told The Associated Press that Roof had drunkenly complained that "blacks were taking over the world" and "someone needed to do something about it for the white race."

Roof faces federal hate crime charges as well as nine counts of murder in state court in the June 17 shootings.

On Aug. 6, Meek received a letter that he was the target of an investigation.
