New York Police Commissioner Ray Kelly said on Monday that Lien would not face charges for hitting the motorcyclists. However, police sources told ABC News on Wednesday that investigators are reviewing all aspects of the conflict, including what happened before and after the helmet-cam video.
"We know in our hearts that we could not have done anything differently, and we believe that anyone faced with this sort of grave danger would have taken the same course of action in order to protect their family," Ng said.
Though she did not give any details, Ng alluded to the fact that individuals stepped into help Lien when he was attacked by at least one motorcyclist after the high-speed chase ended. Lien was treated for stitches at Columbia Medical Center and released, police said.
"We would like to thank the brave citizens who risked their own safety to intervene on our behalf. They truly helped save our lives and prevented my husband from suffering further injury," she said. "We also appreciate and are moved by the outpouring of love and support so many have expressed here in New York and around the country."
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.
