Shares in top mobile carrier Bharti Airtel were down 2.4% on Tuesday after the MoS for Finance said the company was facing investigation under India's money laundering and foreign exchange rules.
"It may not be in the interest of the ongoing investigations to provide any further details," S.S. Palanimanickam told lawmakers in a written reply to a question.
A Bharti Airtel spokesman could not immediately comment.
