Generally speaking, the police do not go so far as to engage in video chats and take off articles of clothing. Most of the police are male officers posing as young females, they can't and wouldn't do a video chat.
Your "friend" was wise to break it off and should never do anything like that again.
Unless the minor comes to the attention of the police for some other reason and then starts dropping names and such, I doubt this will go anywhere.
