The Indian rupee today fell further by 23 paise against the US dollar to trade at a lifetime low of 70.82, reported news agency Press Trust of India (PTI). The free fall of Indian currency continued today on strong month-end demand for the US currency amid sustained foreign fund outflows. At the Interbank Foreign Exchange (Forex) market, the local currency opened a tad higher at 70.57 a dollar from its previous close of 70.59 but slipped to hit a new low of 70.82, down by 23 paise, PTI added.
