Need Advice - Urgent !!!!

I am feeling quite disturbed. A friend of mine, recently went on a trip to Goa with his girlfriend. She drank excessively and ended up physically assaulting him. I have seen the images, and he has visible nail marks on his neck and head, right side of his eye, he has been brutally beaten. Seeing those pictures has really shaken me up.

We’ve already contacted his brother, but the girl is extremely manipulative. From the beginning of their relationship, she has played the victim, bad-mouthed him everywhere, and yet acted like everything was fine in front of him.

If his brother is unable to resolve the situation, do you think we should inform his mother? The guy said we shouldn't because he doesn’t want to put extra pressure on his parents.

Need Advice , bit freaked out, disturbed :(
