Mumbai attack co-accused David Coleman Headley on Wednesday testified that he had conducted a surveillance of the German Bakery in Pune and identified Chabad Houses in Delhi, Pushkar and Pune as potential bombing targets.

The Pakistani-American said this while wrapping up his testimony after five days of questioning by prosecution and defence lawyers in the trial of his childhood friend and 26/11 attack co-accused Tahawwur Hussain Rana in a Chicago court.

On the sixth day of the trial, prosecutors called FBI agents to bolster the testimony of Headley, a Lashkar-e-Taiba operative, who is government's star witness in the trial.

Headley also testified that during the trial he had lied at times about certain events in his life.

Headley said he made a video of the German Bakery which was bombed on February 13, 2010 killing 17 people and injuring 60 others.

The German Bakery was attacked while Headley was under arrest by the FBI.

Headley said he had made a list of Chabad Houses in Delhi, Pushkar and Pune which could be targeted.

The German Bakery is located near the Chabad House and an Osho Ashram in Pune. The German Bakery blast was a part of the Karachi Project — an LeT project with the Indian Mujahideen.

Headley also said he had plans to write a book and make a movie on the events in his life. Rana's lawyer Patrick Blegen said Headley had told several people including his wife so.

“If I write a book, I can make huge amounts of money,” Headley said.

Earlier, Headley had told the FBI that he did not carry out surveillance of the Bakery, but later confessed to agents of India's National Investigation Agency having conducted the surveillance.

Headley has pleaded guilty to 12 terrorism charges related to 26/11 Mumbai attacks and other plots in the wake of his 2009 arrest here.

The Pakistani-American also said he made a “fool” of Rana, a Chicago businessman, by involving him in the 26/11 conspiracy.

“I made a fool of him [Rana]. Poor fellow was stuck in this for no fault of his. I made a fool of him in getting to assist me on what I did,” Headley told Rana's lawyer.

While Headley has pleaded guilty, Rana has maintained that he is not guilty in the charge of “support to terrorism.”

Defence attorneys said Headley lied to the law enforcement agencies and implicated Rana in the plot to save his life.

Headley expressed remorse at the killing of Indian people.
