3 students injured after Chino cop’s assault rifle discharged during safety demo

 Police are investigating how and why an officer’s AR-15 assault rifle was accidently discharged, injuring three students, during Red Ribbon Week activities Wednesday morning at Newman Elementary School.
The weapon was mounted to a police motorcycle that was on display during the activities, said Tamrin Olden, Chino police spokeswoman.
The gun went off at about 11:14 a.m. at the elementary school, 4150 Walnut Ave.
“The event and activities did not involve the display or use or demonstration of any weapons,” Olden said during a press conference Wednesday evening.
