Testifying during the trial of Tahawwur Hussain Rana, a Mumbai attack co-accused, Headley said that he made a video of the German Bakery which was bombed on February 13, 2010 killing at leat 17 people and injuring 60 others.
While Headley was under arrest by FBI, the German Bakery was attacked.
Headley, who ended his testimony, said that 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.
Earlier Headley had told FBI that he did not carry out surveillance of the Bakery, but later confessed to the Indian agents of National Investigation Agency that he had conducted its surveillance.
50-year-old Headley has pleaded guilty to 12 terrorism charges related to the deadly 26/11 attacks and other plots in the wake of his 2009 arrest here.
Headley also said that he had plans to write a book and make a movie on the events in his life. Rana's lawyer Patrick Blegen said that Headley had told several people including his wife so.
"If I write a book, I can make huge amounts of money," Headley said.
