Need help with someone harassing and extortion
My friend has been threatened and harassed online. Long story short. She was in a relationship with this guy who she broke up with as things didnt work out. He happened to have her intimate photos and shared it to his friend. His friend (let's call him Martin) has been making fake profiles on Facebook, Instagram, reddit, and other websites and impersonating her and posting her photos on those websites in groups and pages along the lines of "looking for fun".
He has also made several threats to go above and beyond just this. His latest threat was to nuke her socials and she has been getting spammed with Instagram security code messages.
She changed her phone number after he leaked it publicly.
As her friend. I want to make sure this Martin guy gets behind bars for all this crime. And even his friend (her ex) also have action taken against him.
I have all the screenshot of his messages to her account and even have his personal Instagram and phone number.
Could anybody experienced in this please help guide me on what I can do.
Thank you guys so much
