From the Broward Sheriff’s Office:

The preliminary investigation revealed that a 2009 Honda Accord Sedan, driven by an unknown male, was traveling southbound on Northwest Ninth Avenue (Powerline Road) approaching the 2500 block. At the same time, a Broward County Transit bus was stopped to drop off a passenger. As the bus pulled out to continue southbound, it began to merge into the right thru lane from the edge of the roadway. At that time, the Honda approached the bus from behind. The driver of the Honda failed to allow the bus to merge and passed it, almost striking the front driver’s side as it cut in front of the bus. The Honda then veered right (west) and drove off the roadway and onto the sidewalk and driveway at 2417 N.W. Ninth Ave., striking multiple children.
After the crash occurred, the vehicle accelerated and fled the area southbound.

A description of the vehicle was released among law enforcement agencies, and was located in Wilton Manors.
