This man is extremely dangerous. I would reach out to the police and tell them everything. That you fear for your life and that he is trying to black mail you. He is crazy and I would completely cut off contact from him. Block his phone number, cut ties on social media.
I would believe everything he tells you and then some. Try and hide at someones house until things calm down. There is nothing more dangerous then an angry A. Please take every caution you can. Do not walk somewhere alone. Call someone from your car to come and get you. Please believe him and run and run fast.
