Markets plunged Monday morning following muted trends in other Asian markets, and after exit polls predicted a victory for the Aam Aadmi Party in Delhi.
Besides, discouraging third quarter earnings by some bluechip companies and weakness in the rupee, dampened trading sentiments.
The 30-share index tumbled by 286.49 points, or 0.99%, to 28,431.42. The gauge had lost 963.86 points in the previous six sessions.
In a similar fashion, the National Stock Exchange Nifty dipped below the 8,600-mark by falling 77.85 points, or 0.90%, to 8,583.20.
All the sectoral indices, led by realty, auto, metal and banking, were trading in the negative zone with losses up to 2.18%.
Brokers said sentiments dampened following exit polls showing that the BJP may not be able to form government in Delhi, accelerating selling pressure.
Besides, the depreciating rupee which slipped below the 62-mark against the dollar to trade at 62.05 and a mixed trend at other Asian markets on poor Chinese data, weighed on sentiments, they said.
Among other Asian markets, Hong Kong's Hang Seng index was down by 0.61%, while Japan's Nikkei index was up by 0.19% in morning trade.
The US Dow Jones Industrial Average ended 0.34% lower in Friday's trade.
