In any case, as long as you got the number plate, it should not be an issue with the car being taken away. In fact, it may work in your favour, as it would be seen as a hit and run. However, I'm sure the more legally inclined guys can provide more info and advice.
Just make sure you report it at a police station and provide a description of events and drivers. If the car was registered in the female driver's name, it would be up to her to prove she was not driving at the time, and not your problem.
