An Illinois student is awake and alert after an accidental bump in the hallway of his school left him hospitalized and unable to breathe on his own.

According to a school district representative, Henry Sembner either bumped into or was bumped by another student. The other student became aggressive and assaulted Henry, sending the 12-year-old to the hospital.

Henry's head hit the floor during the attack. He suffered several skull fractures, WLS reported last week.
