Police are investigating a hit-and-run incident in Newark that left an 18-year-old Newark Arts High School cheerleader in critical condition.

Authorities say it happened around 10:15 p.m. on Sunday on the 500 block of Martin Luther King Jr. Boulevard. The JAGS cheerleader team was just returning home from a cheer event and the school bus was parked outside the high school.

Police say that according to the school bus driver, the lights on the bus were activated and the stop sign was out. The driver struck Chiara Jones as she crossed the street and drove off.
