An Illinois high school teacher was arrested after he pulled a gun on a woman that apparently did not place her order quick enough.

Local police informed WSILTV that it all started at the Harrisburg McDonald's drive-thru early last Sunday morning.

Larry Luna was sitting in line when he became impatient and began honking, screaming, and yelling at the woman in front of him placing her order. Things escalated fast, witnesses say, when the woman stepped out of her car and Luna pointed a pistol at her.

"These are just horrible distractions," said Smith. He says Luna has been a Spanish teacher at the high school since 2006, and confirmed the woman involved was the mother of a Harrisburg student.

"Since this is not a workplace misconduct, assuming that it's true, we really have to sit and let this develop," explained Smith.

Luna faces two charges of aggravated assault for displaying a weapon in a public place.

Luna is out of jail after posting $5,000 bond. As a teacher, Luna would have gone through a criminal background check to be certified, and no prior arrest records have been found.

Again, the superintendent says since these are only misdemeanor charges so he'll remain employed at the district while this moves through the court.
