India to request US for info on complaints of Headley's wives

India is likely to send a letter rogatory to the United States seeking copies of the complaints made by Lashkar-e-Taiba terrorist and 26/11 plotter David Headley's two wives about his training with Pakistani militants for a "special mission" against India.

Sources said India will request the American authorities to send details of information shared by the wives of the Pakistani-American about his activities in India prior to Mumbai terror attack, which claimed 166 lives.

A letter rogatory is a formal request from a court to a foreign court for any judicial assistance.

According to a report from Washington, a review being conducted for the Director of National Intelligence James Clapper has found that since 2001 a number of leads emerged about Headley, that if taken cohesively could have busted the LeT plot to attack Mumbai in 2008.

The US intelligence agencies failed to act on at least five instances of warnings since 2001 by Headley's two wives and other sources who had provided tip off about his training with Pakistani terrorists for a "special mission" against India, the report had said.

Union home secretary GK Pillai had also said last month that the Home Ministry was "disappointed" that the US did not provide specific information about Headley, who had plotted the 26/11 Mumbai attacks, even though he travelled here freely after the terror strike.

The US media also reported today that Headley was sent to Pakistan by US authorities to work for them as an informant after 9/11 despite a warning that he sympathises with extremist groups.
