A man accused of leaving an explosive device at a North Carolina airport has been assigned a defense attorney at an initial court appearance.

The federal court docket says that Michael Christopher Estes was advised of his rights and charges by a federal magistrate judge Tuesday. He’s accused of attempted malicious use of explosive materials and unlawful possession of explosives at an airport.

Authorities found the Mason jar filled with explosive chemicals Friday at the Asheville airport and rendered it safe. Estes was arrested the next day.

A federal public defender assigned to the case, Fredilyn Sison, didn’t immediately return messages seeking comment.
