NORTHBROOK, Ill. — A police report shows a high school hall monitor in a northern Chicago suburb had to turn over dozens of firearms after his arrest.

The Pioneer Press obtained Northbrook Police Department records about 60-year-old Steven Schulhof’s arrest Aug. 26 through a Freedom of Information Act request.

Police say Schulhof had a loaded handgun in his vehicle and police-style badge on his waistband when he crashed into a light pole while driving in reverse on Glenbrook North High School’s property. Schulhof told police he had been training his dog at the school.

Authorities say Schulhof didn’t have a concealed carry permit and was in violation of a state ban on having guns on school grounds.

District 225 Superintendent Michael Riggle said Schulhof has been on paid administrative leave from Glenbrook North High School since his arrest.

Schulhof said the school district has treated him fairly but that police have been too hard on him.

“Seventeen years, with a perfect record, and this is what happens,” Schulhof said.

Police collected 40 firearms from Schulhof during an investigation, the Northbrook Star reported. He’s charged with failure to obtain a concealed carry permit, aggravated unlawful use of a weapon and impersonating a police officer.

“I’m not a gun nut,” Schulhof said. “I just had them as investments — that didn’t turn out all that well.”

Schulhof is scheduled to appear in court Oct. 10.
