David Coleman Headley, the Chicago man who had pleaded guilty to scouting targets for the 2008 Mumbai attacks, is being interviewed extensively by the Indian investigators.

The US justice Department in a statement said that Headley, the plotter for the Mumbai attacks, answered questions over seven days.

The publishing of a cartoon that was deemed offensive by many Muslims, he admitted led to the plotting an attack to the Danish newspaper for the same.

Initially denying all the charges against him, Headley, the Pakistani-American, later changed his plea to avoid the death penalty or extradition to India, Pakistan or Denmark.

It is the first time that Indian officials have been granted the right to interrogate a criminal suspect in the US.

As part of the collaboration and enterprise between the United States and India in the fight against international terrorism, the Indian law enforcement was granted straight admittance to interview Headley.

After they infuriated Muslims by publishing cartoons of the Prophet Muhammad, he was first charged with plotting to attack the Danish newspaper, Jyllands-Posten.

After he was told by members of, Lashkar-e-Taiba that he would have to travel to India to carry out supervision duties for the group, he then had changed his name from Daood Gilani in 2006.
