In a latest development to the ongoing investigation into the 2008 Mumbai terrorists attacks case, the intelligence agencies will match the arrested Lashkar-e-Taiba (LeT) suspect Abu Jundal's voice samples with the intercepts available with them.

If the probing agencies manage to prove that one of voices heard in radio intercepts during 2008 attacks belonged to Jundal, it would be another big breakthrough in the case. This would equip Indian leaders at the international platform to grill Pakistan's inefficiency in containing terrorism on its soil and to pressurise the terror-hit nation to take actions against the people involved in it.

The agencies probing the 26/11 attacks case took Abu Jundal into custody early this month from Delhi International airport after being deported by Saudi Arabia on India's request.

Mumbai police officials, who had sought for Jundal's interrogative custody, will also match his voice samples once they secure his custody. Sources said that the multi-agencies probing the terror case have gathered intercepts in which Junal's voice is allegedly heard.

Jundal is touted as a vital lead in the case that has been under probe for over four years now. He is expected to shed more light on the persons and conspiracies involved in executing the audacious Mumbai terror attacks in 2008, in which at least 166 people were killed.

In one of the latest findings of the 26/11 investigation, Union Home Minister P Chidambaram has revealed that Hafiz Saeed, the founder of Pakistan-based Lashkar-e-Taiba, may have been present in a Pakistani "control room" from where the terrorists in India received directions in carrying out the attacks.

Chidambaram on Friday told reporters that Sayeed Zabiuddin Ansari alias Abu Jundal has revealed the existence of 26/11 "control room" in Pakistan and alleged that it had the state support in the investigation.

"Yes, others were also present and we think one of them was Hafiz Saeed," Chidambaram added.

Meanwhile, Pakistan Interior Minister Rehman Malik via twitter said that he was waiting for the investigation report from Indian agencies over Jundal and that he expects to have original passport claimed to have been allegedly given by the government to him (Jundal).

Jundal is said to have travelled to Saudi Arabia on a Pakistani passport. However, commenting on this allegations, Malik has refused that Jundal held a Pakistani passport and said "Such criminals cannot be Pakistani."
