Will there be any punishment for getting a 18 year pregnant 16M?

Not me but my friend 16M met her 18 on insta. She said she was also 16 year old. They met after 3 weeks , went on a date and everything.After some time my friend went to college in other state.

Yesterday she messaged him saying she is 4 months pregnant and he is the father and all.

He has every message from all the Conversations they had. I told him there is nothing to worry about and please tell his parents about all this mess. His family is very conservative .

Is there any way to register case against him? Or just she is freaking him out?

Edit : I am talking to him , trying to calm him down , told him he is safe and if she responds ask her about the pregnancy, is it real. If it is , he needs to tell any adult in his family
