TRIED TO SNATCH THE GOLD CHAIN ON BIKE AT SIGNAL

I WAS WAITING ON TRAFFIC SIGNAL. 2 GUYS CAME ON BIKE AND 1 GUY WHO WAS SITTING BEHIND THAT GUY STAND UP ON SEAT AND PLAN TO SNATCH THE GOLD CHAIN. I SAW THEM IN MY BIKE SIDE MIRROR. SUDDENLY I BLOCKED HIS HAND. THEY DIDNT EXPECT THAT WHEN I SAW THEM. AGAIN THAT GUY TRIED TO SNATCH MY WIFE NECK CHAIN. CONTINUOUSLY I FOUGHT AND HIT THAT GUY HAND. IMMEDIATELY THEY ESCAPED AND MOVED FROM THAT AREA. TOOK 'U' TURN AND WENT BACK IN CHOW KITH ROAD. IT WAS HAPPENED AROUND BETWEEN 4.30PM AND 5.30PM. PEOPLE PLEASE AWARE. I REALLY FRUSTRATED ON THAT DAY. NOBODY IS COMING TO HELP. JUST SAW WHAT WAS HAPPENING WITHIN A AC CAR.
