An Arkansas teenager caught on video walking up to his teacher in class and blowing cigar smoke in his face now faces a harassment charge against him, local news agencies reported Monday.

The video emerged in December, apparently showing North Little Rock High School student Christopher Dunn slowly standing up, taking a drag from the cigar and blowing smoke in the face of science teacher Robert Holley.

Investigators say the 18-year-old actually blew smoke three separate times, Fox 16 reports.

It all started when the teenager refused to finish an exam in the hallway, police say. They add that the teacher started writing up the student when they confronted each other face-to-face.

A campus supervisor pulled Dunn from the room as the teen said, "I'll be back," according to police.
