Some distance from where the anti-Sterlite protesters were, a Tamil Nadu policeman in plainclothes had parked himself atop a police bus. He was armed with what appeared to be an assault rifle and had been seen in photographs, taking aim. On the road below, are a large number of policemen. Some of them wearing bullet-proof vests, some without protection in their khaki and some riot-control policemen. Then, someone decides to send another policeman to the roof of the bus. According to a video released by news agency ANI, he crawls the length of the bus in a few seconds like an expert commando, takes his position and the assault rifle.
