Manual High School was placed on lockdown Tuesday morning after nearly two dozen rounds were fired in the area.
Police say a ShotSpotter alert of 12 rounds went off in the 2400 block of West Proctor just after 11 a.m. A 10-round alert went off in the 2400 block of West Ann a short while later.
The school building and a vehicle were struck by gunfire. Nobody was injured.
"While I am extremely saddened by the recent events, I am just as determined not to allow these external circumstances to outshine the excellence happening in our buildings each and every day," said superintendent Sharon Kherat in a statement.
"Every student deserves access to a safe and productive learning environment, and we will continue to utilize our strong partnerships and safety protocols to provide just that."
Peoria police said they will have a high presence around the school during arrivals and dismissal.
This comes about a week after a 17-year-old Manual student was shot in the leg while walking to school.
