I cannot imagine that the police would pursue this unless there was more evidence that something untoward happened. I have to believe that the witnesses or surveillance video showed something supporting the woman's claims and NOT that she was in need of any kind of immediate aid.

I would recommend you speak only with your attorney on this If it is as you claim, and witnesses from the bar can back that up, then I cannot see the DA pursuing it even if the police might have had little choice but to act upon her complaint.
