Sensex, Nifty tumble over 3 pc; plunges by 1006 points as global equity rout deepens

In its biggest intra-day crash this year, stock market benchmark Sensex plunged by 1,006 points while Nifty fell below 8,000 level in early trade today due to heavy selling by funds amid global sell-off as worries about China's economy deepen.

Asian markets were also in deep red with Shanghai shares crashing 8 per cent on concerns that the Chinese economy was slowing more than previously thought.

Taking cues from global markets, the Sensex nosedived 1,006.54 points, or 3.67 per cent, to 26,359.53-- the biggest fall in day trade in 2015.
