India is investigating whether a Chicago man accused of helping plan the deadly 2008 Mumbai siege was a double agent working for the United States and a Pakistan-based militant group, an official said on Wednesday.
"India is looking into whether Headley worked as a double agent. That is one of the many angles we are probing," a home ministry official said ….
Indian media reported that New Delhi was suspicious because the United States had not shared vital information about Headley's movements prior to his arrest….
Headley could have been a member of the US Drug Enforcement Agency which allowed him to make frequent trips to Pakistan and gain access to the Lashkar-e-Taiba (LeT) militant group.
The Times of India reports that Indian officials suspect that the CIA knew about Headley’s link with the banned Pakistani militant outfit, Lashkar-e-Taiba, one year before the Mumbai attacks, but did not alert Indian agencies.
The [Indian] investigators believe that the US agencies kept away the information from India and never allowed the Pakistani-origin Headley to get "exposed".
The 39-year old terror suspect, arrested by FBI for his role in Mumbai attacks, had visited India in March 2009 – four months after Mumbai attack carried out by LeT – but FBI still did not inform India that Headley is a LeT operative, apparently fearing he could be arrested in India.
