A shot was fired outside Whittier Elementary School, 295 S. 10th, near 10th and Ivandale, on Wednesday afternoon.
A bullet hit the building, and there were no injuries, a school district official said.
David Smith, spokesman for the school district, said shots appeared to be fired from a passing car, and when the shots were heard the school went on lockout. The doors were locked, the blinds closed and the students stayed inside until they got the all-clear from police, he said.
He said the incident happened right before dismissal, around 1:55 p.m. before the 2 p.m. dismissal, so students waited a little longer than the normal dismissal time.
Smith said persons at the school heard multiple shots.
