Authorities are wondering what prompted a 24-year-old Evanston man to leap from a second floor inside Schaumburg's Woodfield Mall Saturday afternoon, sending him to a hospital.

"His injuries are not life-threatening," said Schaumburg Police Sgt. John Nebl.

Nebl said it was about 4:30 p.m. when officers were called to the first floor of the mall, 5 Woodfield Mall, outside of J.C. Penney for an injured person.

"It appears he jumped from the second level down to the ground level," Nebl said. "Why he jumped we don't know at this time."

Nebl said the 24-year-old man was taken to St. Alexius Medical Center in Hoffman Estates with injuries, including to his back, that are not considered life-threatening.

It was not known how high he fell from, but Nebl said no one else was hurt.

"It's a ways up — one story or probably a little higher than a house or office building," Nebl said.

The man was with someone at the time and officers learned through that person and from witnesses who saw it inside the mall that he had leaped on his own accord.

He is not facing any criminal charges or citations, Nebl said.

The mall was not closed after the incident.
