Women of Reddit, please help!

A guy is harrassing my friend

So my friend (F19) was in a relationship with this guy for quite a few years.

He broke up with her claiming she has a lot of male friends in her college.

Later, he messages her asking for money saying "I spent 10k on you and I need it back"

She said "Why are you doing this?"

And then he showed her photos of both of them making out and said that he will send it to her father.

Now, if her father finds out then it'll be a big problem for her career and he will make her drop out of college.

She was really scared and gave him the money.

Now, that guys is messaging her again that he wants her to come at his place to do god knows what on Valentine's Day. Or she could pay another 4k Rs by the evening or else he'll send those photos to her father.

She said she has her exams on 14 and she can't come. Plus she doesn't have anymore money.

The guy has gone crazy and he's not listening to her.

I told her to tell him that she'll meet with him at her hometown on the day after Valentine's Day (15th) so that me and my boys could get him and she don't have to worry about her exam.

But he's not in the mood of negotiations.

I told her to grab all the screenshots of blackmailing as a proof. It's the least we can do right now.

We need real help so I'm open for any advice right now.

NOTE: BAJRANG DAL IS NOT AN OPTION

**UPDATE: First of all, thank you to everyone who gave their advice in the comments. I was getting tons of notifications so I couldn't respond to everyone.

I called the guy and told him that we have enough proof to file a case against him, he has no chance of winning. So I basically told him that whatever amount he took from her "unethically" by blackmailing her, he must return it before midnight. Or else she's calling the women's helpline tomorrow to mess him up.

Yet after all those warnings he was scared enough but still said he ain't gonna pay her back. I did get a call recording of him claiming he did blackmail her.

My friend was scared a lot but after I showed her the responses from reddit. She's motivated enough to file a case against him. As far as I know, she's been through a lot of physical abuse, harassment and mental trauma by him. I bet you that she won't have a second thought about filing a case against him and she'll ruin him for what he did to her.

Thanks to everyone, she can at least study in peace for her exam tomorrow.**
