The alarm went off at Highland View Elementary School about 1:15 a.m. Dec. 4, after a brick was thrown at a window.
Greendale Police responded after the alarm went off.
Once on scene, police noticed a man near the school. When police tried talking to him the man took off on foot into the "O" section—running out of his blue Adidas shoes.
He was last seen wearing a black jacket with fur lined hood.
Police determined that the school might have been entered but nothing has been reported stolen.
