got a DM saying "we have a video of you", what does one do

woke up this morning to a message on a burner ls profile saying "we have a video of you and your wife from the saturday before last, transfer 1500 to this btc address by friday or it goes to your linkedin contacts". no proof of life, no still, no nothing, just text. we did play with a couple that saturday and the meet was at a hotel so theres no venue to point fingers at. could be a bluff, could be real. im sat at my desk shaking trying to act normal at work. do you respond asking for proof, do you ignore entirely, do you go to police first... my brain is fried and i need somewhere to start
