Authorities say a jailed North Carolina man facing accused of an arson attack on an immigrant-owned store didn't appear in court as planned because he's being disciplined.

An appearance scheduled Tuesday for 32-year-old Curtis Flournoy has been reset for April 21, when the suspect will have a bond hearing.

Mecklenburg County Assistant District Attorney Alana Byrnes said he didn't know what led to Flournoy's being placed on disciplinary detention.

Flournoy remains jailed on a $35,000 bond on charges, including ethnic intimidation and burning a commercial building. It's not clear if he has an attorney.

Authorities say a fire was set Thursday but burned itself out at a market selling goods from the Indian subcontinent. No one was hurt, and authorities said a threatening note was left on the scene.
