Almost this death would have been done by Robbers , looters who would have assumed that he has money. I know my relation brother [engineer] , went to England when he passed o-level exam in srilanka. He was a karate black belter at that time also. When he was in London , as a part time job, he worked in a petrol shed as a security. One day night robber looters about seven people came to loot the petrol shed in the night . My relation brother Karate black belter gave a fight with those seven robbers and robbers got hurt and ran away. My brother saved upon Karate.
