The frightening incident was recorded on a helmet camera and went viral.
Here is the full text of the statement, which appears to have been written by Alexian Lien's wife:
" Our plan last Sunday was to celebrate our wedding anniversary by having a nice family day out with our two-year-old daughter. Unfortunately, instead, we were placed in grave danger by a mob of reckless and violent motorcyclists.
"Our sympathies go out to the injured motorcyclist and his family. However, we were faced with a life-threatening situation, and my husband was forced under the circumstances to take the actions that he did in order to protect the lives of our entire family. 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 two-year-old child. 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.
" 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. 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.
" We would ask that the public and the media to respect our privacy at this difficult time and allow my husband to recover from his injuries. From here on forward we would ask that any further inquiries regarding this unfortunate incident be directed to our lawyers Nicholas J. Massimo and Frank C. Panetta."
