A spokesman for New York Police Department has confirmed that a driver who hit a British tourist, seriously injuring her legs, has not been arrested or charged.
The circumstances are still under investigation, whether it was some sort of rage or an accident. It looks like her leg or part of it was severed during the accident.
He said two other people - the driver and a cyclist involved in a collision which caused the taxi to veer on to the pavement - were also treated for injuries.
