Highland Park High School in University Park was dismissed early on Wednesday after .22 caliber bullets were found in a boys bathroom. No weapon or note was found with the bullets.
The school district at first said that a box of .22 caliber shells was found but later described them in a message to parents and staff Wednesday night as a "handful of .22-caliber bullets."
On Wednesday, the school closed all but front doors on Emerson Avenue and the student entrance on Westchester Avenue in wake of the threatening note found on Tuesday. Thursday, students will again only have these entrances to the building.
Because the bullets and previous incidents including threatening notes were found in bathrooms, restroom access will be restricted.
"Students will only be allowed to use restrooms during passing periods. Those who need access to restrooms during class will be escorted by a staff member," Principal Walter Kelly said.
The FBI and University Park police are investigating the incident.
