My business partner emptied our joint business account and vanished. What can I do?

I run a small tech startup in Bengaluru with a partner. Last week, I discovered that he withdrew ₹25 lakh from our joint business account and is now unreachable. He isn’t responding to calls, emails, or WhatsApp messages. This money was meant for salaries and operational costs. I feel betrayed and unsure of my next steps. Can I file a complaint under criminal law or should I take civil legal action? Is it possible to freeze his personal assets immediately to recover the funds? Please guide.
