BJP general secretary Gopinath Munde on Sunday said that his party would not allow any official of the Pakistan's Inter Services Intelligence (ISI) agency to "step into Mumbai".
Prime Minister Manmohan Singh had earlier asked the Pakistani authorities to send the ISI chief to India to aid the probe of Mumbai terror attacks.
"We do not agree to ISI chief or any other official of that agency coming to India for probe. We will not let anybody from ISI to step into Mumbai," the BJP leader said in a statement.
The statement said that ISI had hand not only in the 1993 Mumbai blasts but also in 90 per cent of the blasts across the country.
"Inviting ISI for probe is like handing over treasury keys to the thief," Munde said.
To Union Home Minister Shivraj Patil's resignation, Munde said that it was 'too late' and Patil should have quit after the Delhi blasts in September last.
