Maricopa police are investigating a school bus-involved accident on southbound John Wayne Parkway, just north of the railroad tracks Tuesday afternoon.

Three children were on board the Maricopa Unified School District bus that was transporting students after the second day of school, said Maricopa Fire & Medical spokesman Brad Pitassi.

A blue Ford truck was involved in the accident as well, and sustained minor damage to the front of the vehicle, Pitassi said, adding there was no damage to the bus. Although MFMD reported the children did not sustain injuries, Pitassi said two of the minors were transported to Chandler Regional Center as a precaution.

“When parents of minors aren’t on scene, we ask them. And a lot of times if there is an accident they say, ‘Take them to the hospital’,” Pitassi said.

The three adults on the bus and the driver of the truck refused medical attention and reported no injuries, Pitassi said.

According to MPD spokesman Ricardo Alvarado, the incident is being investigated as a possible DUI, and the driver of the pickup was detained.
