I do not see a violation of the ARD program unless the girls were underage and the police officer decides to charge you with corruption of minor. You need to be very careful while on probation.
Your post is a wonderful illustration of why citizens should not speak with police officers on their own. Do not post any further details on this public website or anywhere else on the Internet, including social media like Facebook. My Keller mentions one of the possible negative scenarios; there are others. You might want to prepare yourself in advance by speak PRIVATELY with qualified criminal defense counsel in your area. Otherwise it will be a waiting game to see what, if anything, comes of this incident. Good luck.
You could be in trouble independent of the ARD violation. If the police want to talk to you again, or if charges are filed against you, you need a criminal defense attorney.
This answer does not constitute legal advice and does not establish an attorney-client relationship.
I agree with my colleagues, if the police contact you again do not speak to them without counsel, if no one contacts you consider yourself lucky.
