(AP) — A June trial has been set for a 23-year-old man accused of threatening three students at Northeast Community College in Norfolk.

John Ertzner pleaded not guilty on Monday in Madison County District Court.

Officials say an armed man approached three students at the school early last month. A court affidavit says the students reported that the man followed them on a campus road and stopped next to them when they stopped, pointing a gun at two of them.

Ertzner told an investigator he mistook the three for other men who’d chased him earlier in Norfolk. He said he’d put his BB pistol on his car console but didn’t point it at the students.

His trial is scheduled to begin on June 9.
