I want to help the 'hero' who saved my life.

Hi, my name is Hikari. I would like to ask for help for the person who protected me when I was walking down alone in the streets. He is my co-worker at McDonald's and we get along, he is a really good person who loves helping others, a good student and son to his parents. Last night, when we were walking home together from work, there were two men who suddenly stopped us, it was raining really hard and there are no other people on the street except us. My friend immediately grab me and hid me behind him. We were confronted by those people and said I should go with them and we'll have fun. I got scared and hid behind my friend more. They went closer and suddenly punched my friend on his face. I didn't know what to do at that time, I was standing there frozen like a log while my friend is stopping them from getting near me. We got lucky when there were police officers who were patrolling around the area who found us. The two men immediately ran away before the police could catch them...

On the morning, my friend together with his mother went to the hospital and they found out that his jaw had a bone fracture and his wisdom tooth was removed as well, the doctor said that they need to put a permanent metal support on his face and braces as well that costs almost $1200.

I am desperately asking for help with this, we don't have enough money to cover all the expenses. Any amount is truly appreciated. I hope that you could help my friend who saved me from danger.
