The Indian equity benchmarks fell for third straight session on Friday dragged by weakness in information technology, pharma and consumer durable shares. The Sensex fell as much as 495 points and Nifty 50 index touched an intraday low of 17,077. For most part of the day, benchmarks traded lower and extended losses in afternoon deals. However, buying at lower levels in the last 30 minutes of trading helped benchmarks stage partial recovery.
