The 30-share index, which lost 324 points in the previous two sessions, dropped further by 92.09 points, or 0.53 per cent, to 17,388.74 in the first few minutes of trade today.
The wide-based National Stock Exchange Nifty index also shed 19.15 points, or 0.36 per cent, to 5,238.80. Brokers said the trading sentiment remained bearish, taking cues from a weakening trend in other Asian markets following overnight losses in the US amid fresh fears over the European debt crisis after Greece announced a referendum on its latest bailout deal.
In addition, the possibility of another petrol price hike cast a shadow over the trading sentiment, they said. In the Asian region, Japan's Nikkei index was down 1.93 per cent and Hong Kong's Hang Seng Index by 1.72 per cent in early trade today.
The US Dow Jones Industrial Average fell by 2.48 per cent in yesterday's trade.
