CHINO, Calif. (AP) — Police policy was not followed leading up to a school assembly where a student pulled the trigger of an assault rifle mounted on a police motorcycle and three children were injured by bullet fragments, authorities said.
Department rules state the rifle chamber should be empty when it is mounted, Police Chief Miles Pruitt said in a statement late Thursday.
"The preliminary investigation has shown that the established safeguards and procedures were not followed," Pruitt said. "It is unfortunate that this event occurred and I will make every effort to ensure it does not happen again."
The AR-15 was locked to the side of the motorcycle that was on display at Newman Elementary School on Wednesday during an anti-drug program when a student managed to fire it, Chino police spokeswoman Tamrin Olden said.
