David Coleman Headley, arrested by the FBI for planning a terror attack against Delhi, spent a fortnight at a hotel in South Mumbai in 2006.
 
Headley checked in using his own name at Hotel Outram.  Hotel authorities say at that time, they had submitted documents to the Mumbai police as part of the standard procedure of sharing information on foreigners staying at the hotel.
 
The Mumbai police has confirmed that Headley visited Mumbai at least four times; his accomplice, Tahawwur Hussain Rana, had also visited India. Rana and Headley were both arrested in Chicago last month.  Headley allegedly exchanged several emails with top operatives of terrorist group, Lashkar-e-Taiyaba. 
 
Headley, a US citizen, lived for several years in Pakistan.  He was about to catch a flight to Pakistan when he was arrested at Chicago's O'Hare airport.
 
The Mumbai police says Rana and Headley also met in Mumbai.  Between November 2006 and July 2008, Headley also reportedly ran a firm by the name Immigrant Law Centre at the AC Market. The police says that officially, the firm helped applicants to get visas for the US and Canada
 
A team of Indian officials is in America to interrogate Headley.  It has already been revealed that he planned to attack the National Defence College in Delhi.
