A Round Lake Park man has been charged with aggravated assault and unlawful use of a weapon after threatening to stab another man outside a school, authorities said.
Shawn W. Techen, 39, of the 500 block of North Greenwood Avenue, was arrested Tuesday following an altercation on Greenwood Avenue, just north of W.J. Murphy School, Round Lake Park police said in a news release.

Authorities said officers directing traffic at Murphy School at 3 p.m. observed a Ford Explorer driven by Techen illegally passing a school bus that was loading students.
When officers stopped the vehicle, Techen told them he had been assaulted moments before, authorities said.
Officers investigated and learned Techen had confronted a woman about the way she was parking on Monday, March 11, as she was picking up her child at the school, authorities said.
The victim told her husband about the confrontation with Techen, and the husband accompanied her to the school the next day. The man confronted Techen, police said, and during the argument, Techen brandished a dagger-style boot knife and threatened to stab him.
In addition to the aggravated assault and unlawful use of a weapon charges, Techen was charged with driving while license was suspended and passing a loading school bus, officials said.
He is scheduled to appear in court April 9, authorities said. Bond information was unavailable.
"We take any criminal incident that occurs on or near school property seriously," Round Lake Park Police Chief George Filenko said. "Officers are routinely assigned to the school every day at drop off and pickup and also do walk-throughs during school hours."
