Physically Abused, What Should Be My Next Step .

I currently reside in Delhi and recently physical abused. It was for some petty issues while I was playing a cricket match. It started from a heated argument with the guilty person, his age would be 18-19 years. While playing he orally abused and then it got wild,there was not much of physical fight on the first attempt but on the second time when I insisted to compromise and talk and cool down this matter he came with some bunch of boys started to beat my face with some metal bangles, that drenched me in blood. Please suggest me on the above-mentioned incident.
