The 30-share barometer, which had lost over 118 points in the previous two sessions, fell further by 112.82 points, or 0.58 per cent, to 19,452.10, led by losses in stocks of consumer durable, auto and information technology sectors.
Similarly, the wide-based National Stock Exchange index Nifty declined by 26.45 points, or 0.45 per cent, to 5,887.65.
Brokers said sustained selling by funds amid a weak trend in Asian regions mainly influenced the trading sentiment here.
