School bus carrying special needs children involved in chain-reaction crash

ELIZABETH, New Jersey (WABC) -- A chain-reaction crash involving a school bus with young children inside led to some scary moments after one driver took off running after the collision Wednesday in New Jersey.

"He went so fast. That was so quick!" said Ronnie Bontemps, a witness.

It happened right outside of Bontemps window.

A wild sequence of events ended with school bus full of kids getting slammed by a speeding car.

Then, a car smashes into a minivan.

Both of those vehicles then rock the bus.

Bontemps was cutting hair at a barber shop when it happened.

He says those young kids were crying and in shock.

"That was a big impact. That was a big impact," Bontemps said. "But there was so much kids screaming in the bus."

It happened at Madison and Fairmount Avenues around 3 p.m. Wednesday in Elizabeth.

It didn't end there.

The driver of the speeding car then took off running.

Police said the video showed the end of a police pursuit.

They say the suspect dropped drugs as he ran and had more drugs on him when cops caught up to him.

Witnesses say the chain reaction caught everyone off guard, with cops cornering the suspect within seconds.

School officials say seven special needs children on the bus were not hurt but very shaken up.

They were rushed to a nearby hospital as a precaution.

The driver of the minivan sprained his ankle.

Three others in his minivan were unharmed.

Police are continuing to investigate the incident.
