Central security agencies have located the mobile phone number used by David Headley, arrested by FBI for his involvement in an LeT plot to carry out attacks in India, during his stay in Mumbai.
The clue to the mobile phone used by Headley was given by a 38-year-old Parsi lady who was working with him at his immigration services office set up in Mumbai, official sources said.
The security agencies have already started analysising the call records of Headley who has been arrested by FBI on October three for allegedly hatching a conspiracy with Pakistan-based terror group Lashker-e-Taiba to carry out strikes inside and outside the US.
This may also help the security agencies to ascertain whether disappeared cadres of banned SIMI and Indian Mujahideen had used Headley's immigration services.
The phone number had come as a boost to the sleuths who were rattled by the fact that Headley, who came to India nine times since 2006-07, had wound up the entire immigration business in April this year and they could not get a single information about the functioning of his business and clients.
The mysterious disappearance of many terror accused from Gujarat, Madhya Pradesh and Hyderabad including that of Rahil Sheikh, an alleged mastermind in the 2006 Mumbai serial blasts that left 187 people dead, was also being looked into.
