NEW DELHI: Sustained joint efforts by Indian and US security agencies seem to have driven underworld don Dawood Ibrahim into hiding close to the Pakistan-Afghanistan border Top sources in country’s security establishment, involved in tracking the activities of the D-Company, said that Dawood had been whisked away from his high-security mansion in Karachi’s Clifton area by Pakistan’s Inter-Services Intelligence ( ISI ) and shifted to an undisclosed location close to the Af-Pak border.Indian intelligence agencies, keeping close tabs on movement of Dawood and his men, received specific inputs over the past few days about the gangster shifting base."Dawood seems to have gone completely underground. He has not been seen or even heard of interacting with his close aides. The Inter-Services Intelligence and Dawood appear under a lot of pressure," sources in the intelligence community claimed. Sources added that Inter-Services Intelligence appeared extremely wary of the new Indo-US cooperation to fight terrorism, with special focus on targeting the D-Company network.This had come up during he extended dialogue between National Security Advisor AK Doval and state department officials in the US earlier this month. Sources said that cooperation on Dawood would be the first test of the partnership between the two countries with US playing a crucial role in choking the funds to the DCompany. The mastermind of 1992 Mumbai terror attacks and many more subsequently has business interests around the world, including in UAE, Africa and Pakistan. It is suspected that Dawood has been using money raised by smuggling narcotics to fund terror activities in Afghanistan and India
