I was causally having my bachelor party in one of the shacks in ECR, when suddenly a fight broke out and it turned out to be my friends. They were sloshed and were getting beat badly. I had to intervene and asked them to stop this as we were leaving. Out of nowhere one person upper-cut me on my face and now I have to get a few stitches on my face. After that they ran away. I have the persons car number and everything. How do I deal with this without a police complaint? I don’t want to deal with any cases during my wedding time. Even the owner of the shack was not co-operative and wanted us to leave and he called the cops on us. The cops are useless as ever. Is there someone who can help me get this guy !?
