Mumbai: The rupee fell to as low as 61 per dollar on Friday, its weakest level in three months on the back of a recent rally in the US currency in global markets and falls of more than 1 per cent in domestic share indexes.

Dealers said they suspected some mild dollar sales from state-run banks on behalf of the Reserve Bank of India to prop up the rupee. The partially convertible rupee fell to as low as 61.08 per dollar, its weakest since April 25. It was trading at 61.06/0750. The broader Nifty was down 1.5 per cent.
