JERSEY CITY, N.J. (CBSNewYork) – A child was in critical condition Saturday after being struck by a car in Jersey City, police said.

Police said the 8-year-old boy and another pedestrian were hit around 4:30 p.m. at Christopher Columbus Drive and Grove Street.

Witnesses said the child was crossing the street with a family member and group of kids from his double-Dutch team.

“They never made it to the sidewalk, because the person that was driving the car just mowed them down,” one man said. “The child was just out, just laying there, like lifeless.”

The driver stayed on the scene, police said.

But witnesses told CBS2’s Jessica Borg they had to step in to stop the driver.

“He was basically about to do a hit and run,” witness Israel Paterson said, adding her coworkers chased after the car. “They was running after the car saying, ‘stop the car, stop the car!'”

The boy’s aunt fell to the ground in despair.

“All she could do was just cry,” said witness Angel Alvelo. “She was just crying. She was on the floor crying.”

He described the driver as a man in his 40s, who didn’t say much when pedestrians forced him to stop and called police.

“There was no reaction, there was no remorse, there was no tear in his eyes,” Alvelo said. “It was just like nothing happened for him.”

The child was rushed to Jersey City Medical Center in serious condition. The second victim refused medical attention.

The cause of the crash remains under investigation.
