A 9-year-old boy visiting New York City for the holidays will remain hospitalized "for quite some time," the boy's mother said after they both were pinned by a taxi cab on Christmas Day.
"[It] hit us from behind. Didn't even know what had happened," the 41-year-old mother, who was visiting with her family from Australia, told New York ABC station WABC. "I just remember being on the ground and something on top of me. I could hear the wheels screeching and my son screaming next to me."
The taxi cab jumped the curb and struck six pedestrians in Herald Square shortly after 4 p.m. on Christmas Day after the 58-year-old driver suffered a medical emergency, police said. All impacted pedestrians suffered non-life-threatening injuries, with three -- including the mother and son -- transported to area hospitals, officials said.

"I ran over and noticed there was a little boy, his leg was underneath the front passenger tire as it was spinning," Tucker told the station.
One man shut the car off, according to Tucker.
"There was a whole group of us that ripped the fender off, lifted the car back, and then that's when I kind of grabbed the little boy," Tucker told WABC.
Tucker, who was visiting from Oregon, told WABC that his wife was also struck by the taxi on her back shoulder. He said he ensured his wife was OK before joining others to help the mother and son.
