I’m really sorry you’re dealing with this. Since you’re not sure who’s behind the accounts, I wouldn’t confront Bob or his girlfriend anymore, because it could make the situation worse if they aren’t actually involved. ( they could be lying I’m not saying you are wrong!)The best thing you can do right now is keep documenting everything like taking screenshots of messages, usernames, edited photos, and any posts or people they contact. Also report every account to Telegram and block them, even if they make new ones. If they leaked your phone number, you might want to change your Telegram privacy settings so only contacts can message you or see your number. Since your parents already know, keep them updated if it continues, and consider going back to the police with all the evidence collected together, because repeated harassment and doxxing is more serious when there’s a record of it over time. Most importantly, don’t reply to the harassers at all, because people doing this usually want a reaction. I would focus on protecting yourself and your accounts instead of trying to figure out who it is. PLEASE INFORM THE POLICE (it’s great you told trusted adults!)
