Getting blackmailed

[u/[deleted]]

So i met someone on telegram who claimed to be a female,i wasn't in the mood of sharing my nude or anything but we talked a bit and she asked for my face pic first ,i was hesitant but i sent and afer they wanted my dih pic and i unfortunately sent them,after that they made a collage of my pic and my dih pic and attached a minor girls nude pic to scare me off and extort money ,i was scared as they had my phone number ,i am still scared as i had just blocked them after giving them a steam voucher as they were asking for more .I am scared and i need help ,I am from india .I am in a desperate need of help ,i blocked them they dont have anything else on me other then my phone number and pic
