Ng placed four calls from inside the Range Rover in a span of nine minutes, ending as ambulances and police finally arrived at the site where Lien was assaulted.
Bystanders intervened and helped to stop the assault when the bikers, angry over the confrontation, attacked her husband, Ng said in her statement. Six minutes of the confrontation were captured on video taken by a motorcyclist's helmet camera and uploaded to the Internet.
"Our fear for our lives was confirmed when the incident ended with the ruthless and brutal attack on my husband, me, and, most importantly, our 2-year-old child," Ng said in the statement.
Christopher Cruz, 28, of Passaic, N.J., is the only biker charged so far in connection with the investigation. Cruz was the motorcyclist who slowed down, resulting in the SUV's bumping him, according to police. Cruz was charged with reckless driving and false imprisonment. It's unclear whether he has entered a plea. He appeared in court briefly today and is scheduled for another court appearance on Oct. 24.
Ng said her family's sympathies went out to Mieses, who broke both legs and suffered spinal injuries. Mieses' wife said the injuries he sustained might leave him paralyzed.
No additional arrests have been made in the case. One motorcyclist seen on the video banging on the SUV's window turned himself into police earlier in the week and was questioned and released, police said.
