Someone groped me in the bus?

At first he was just trying to touch my hand. He was like linking his fingers to mine. So I just pretended to fold my arms so he would not be able to touch me. Then I felt his hand on my and he suddenly squeezed it. I got so pissed off that I punched him in the face and kick him in the . He had to go to the hospital for it. I broked his nose and . He said his going to sue me. What charges will I face? Their were some witnesses on the bus but I don't know those people. And that pervert really deserves it! What if I'm not the only woman he groped. I'm not just defending myself but other women as well. Women shouldn't experience this!
