As share prices rose to an all-time high, bomb threats were received by two key India’s stock exchanges on Monday.
"The e-mail threatened to blow up the NSE and the BSE," Deshmukh said.
The threat was received on Monday, but it didn't affect trading in the two stock exchanges.
"We are taking all precautions. This will not affect trading tomorrow (Tuesday)," he told The Associated Press.
The e-mail came in the name of Abdul and police were investigating, Deshmukh said. Similar e-mail threats have been received in the past as well.
Earlier this year, police arrested one person living in the northern Indian town of Meerut town for sending a similar e-mail. If convicted, he can be jailed for five years.
