New Delhi, Nov 14 (IANS) The probe to find out Lashkar-e-Taiba (LeT) suspect David Coleman Headley's role in planning the Mumbai terror attacks took off after Indian intelligence officials obtained "good leads" from their American counterparts, Home Minister P. Chidambaram said Saturday.

The home minister said this while speaking to reporters at the Ambedkar Stadium here.

"Investigation is on (to find Headley's role in 26/11), and once the probe agencies complete their work, we will share whatever has to be shared," Chidambaram said.

"This is not a cricket match which gives a ball-by-ball description," he said when asked to give more details on whether Headley is turning out to be one of the prime suspects in the probe into 26/11 - whose first anniversary will be observed soon.

Headley, who is in custody in the US, had changed his name from Daood Gilani in 2006. He alongwith his accomplice Tahawwur Hussain Rana, a Canadian citizen of Pakistani origin, were arrested in the US last month by the Federal Bureau of Investigation (FBI) for plotting fresh terror attacks on behalf of the LeT against India.

Chidambaram said the Indian team of intelligence officials who went to the US in connection with the probe into Headley's terror designs against India had come back with "good information".

"The team had a good visit. They have come back with good information," the minister said about the US visit by a team of officials from India's Research & Analysis Wing (RAW) and the Intelligence Bureau Nov 1 to question Headley.

The team was keen to find out if Headley was in touch with the masterminds of the LeT and if he attended any of the training camps that the 10 Pakistan-based terrorists went through for the 26/11 attack in Mumbai.

Apparently, objections from Headley's lawyer questioning a foreign agency's involvement in the interrogation came in the way.

But Chidambaram last week said questioning Headley "was never on the agenda" of Indian investigators.
