Have managed to get a NBW Non Bailable Warrant issued. Now what do I do?

Briefly: a NBW is being issued today in a different state. FIR under Sect. 506, Criminal Intimaidation.

Precis: the person served on is a PIO/NRI? and my visa sponsor. Turned out to be a nightmare. Criminal breach of trust, he refuses to re-imburse my travel + living expenses overseas as promised in writing by him to the ( foreign country) goverment's Visa Office. Several vicious verbal threats and serial bullying while in his presence overseas, witnessed by locals there. Huge "I am a millionaire NRI, you are all poor Indians; I can buy anyone off in India" complex

I have the copy of his letter to the Visa Office, his passport copy ( he is a PIO or NRI, Indian passport , resident overseas for several decades). Instead of re-imbursement there have been  a serious of threats both verbal and e-mail. Based on the latest e-mail threat and more, an NBW has been issued. The person is currently in India, in a different state.

The warrant officers will serve the warrant today. I request Prajas here to advise me on the next step, realistically speaking. It is my first MBW issued. The person concerned is has a severe personality disorder, *extremely* vindictive and a classic case Jekyll and Hyde Personality Disorder

Questions:

what if he ignores the warrant? Can he?

what is he hides?

what if he attempts to buy himself out?

what if he makes a relative pose as him?

Can the police block his exit from India?

Any suggestions or help will be most welcome
