As you said, it was a crowded area where it could have been anyone. If she identified you, the police would have either taken you into custody and to the jail to book you, or would have written you a citation and given you a notice to appear, at a future court
date. At this time, it is unlikely they will charge you. They took your information as a formality, in case they need to follow up with a complaint
. It is possible that the women said she did not want to pursue the incident, no matter who she was touched by. In the event that you do get charged, you should receive a summons in the mail, with a court date. You will be entitled to call witnesses to testify on your behalf at trial
. You can fight this charge. At this point in time, there is no need to worry. If the police wanted to speak with you, they would contact you. If charges were filed, you would need notice, as to not violate your due process rights. This sounds like an isolated incident which the victim did not wish to pursue.
