Meanwhile, Sergio Consuegra, who is seen in NYPD fliers with his arms stretched out protecting Lien from the bikers, was honored in Washington Heights today for his bravery.
Consuegra told ABC station WABC-TV in New York that he intervened in the beating when he saw a biker grabbing Ng through the car window, telling her, "You're going to get it too."
Newly released photos show the SUV's passenger side window where Ng was sitting was smashed in, as well as the driver's side window.
"At that moment, I said I have to do something," Consuegra said. "There's a family in danger here and they're going to get killed. Nobody intervened in this situation and nobody's stepping in."
Consuegra said the biker left Ng alone after the crowd began screaming for help. Then, he said he saw a badly bloodied Lien on the ground, getting bashed in the head with a helmet.
"I went up there, right away to them, and I stood in the middle," he said. "I went, 'No. No, that's it. Let it go guys. You did what you did.'
"Then somehow, one of them moved, started moving and I said, 'Yeah, this is enough now,'" he said.
