GLENVIEW, Ill. (CBS) — Two schools in Glenview were closed for the day on Wednesday, after authorities found what they originally said was believed to be a small explosive device that had gone off in the parking lot of a hospital nearby. But officials later said it was only a fire.
Officials at Glenbrook Hospital in Glenview said the fire was reported around 4 a.m. in a western parking lot of the hospital. The fire was put out right away.
Police originally said the fire was the result of a small explosive device going off in the parking lot, but they later said it was just a fire.
Police Sgt. Dave Sostak said later Wednesday that the Cook County Bomb Squad determined there was no incendiary device. Sostak would not say what was on fire, other than that one of the items was a metal container.
No one was injured in the explosion, and there was only minimal damage to the parking lot surface, police said.
Police arrested a 20-year-old Niles man in connection to the fire. Leonard Reinebach was arrested at his home and charged with criminal damage to property and disorderly conduct, a police release said. Reinebach was released on a $1,000 D bond and is scheduled to appear in court April 13.
The safety of patients, employees and visitors at the hospital was never in jeopardy, according to the hospital.
The hospital never closed, but early-morning elective procedures were delayed.
But as a precautionary measure, Glenbrook South High School, 4000 W. Lake Ave., and Winkelman School, 1919 Landwehr Rd., both closed for the day.
A notice on the West Northfield School District 31 Web site said Winkelman, an elementary school, is closed because police need to conduct a thorough search on the school building and grounds. The notice did not indicate why the search was mandated.
A notice on the Glenbrook South Web site only said school was canceled “to allow for more information to be collected.”
The Cook County Bomb Squad and representatives from the Department of Homeland Security are assisting Glenview police in investigating the explosion.
