He was arrested Feb. 10 in the northern city of Rampur after suspected Muslim militants attacked a police camp, killing eight constables. He said he was there to collect weapons to bring to Mumbai for a future attack.
Yash said Ansari's arrest did not derail Lashkar's plans for an attack. "When they found that their mole in Bombay had been caught...they carried out the operations in a different way," he said.
Meanwhile, police officers said they were trying to get as much detail as possible from Kasab.
"A terrorist of this sort is never cooperative. We have to extract information," said Deven Bharti, the head of the Mumbai crime branch.
Indian police are known to use interrogation methods that would be regarded as torture in the West, including questioning suspects drugged with "truth serum."
Bharti provided no details on interrogation techniques, but said "truth serum" would probably be used next week. He did not specify what drug would be used.
During questioning, details of Kasab's recruitment by Lashkar began to emerge, said police, describing him as fourth grade dropout from an impoverished village who was gravitating to a life of crime.
"Lashkar recruited him, preying on a combination of his religious sentiments and his poverty," said Maria.
The revelations came as Secretary of State Condoleezza Rice met with leaders in Islamabad after visiting India's capital — part of a U.S. effort to pressure Pakistan to share more intelligence and pursue terrorist cells believed to be rooted in the country.
Pakistani President Asif Ali Zardari promised Rice his country would take "strong action" against any elements in Pakistan involved in the siege.
On Thursday, the U.S. Treasury Department designated as terrorists four individuals who hold leadership positions in Lashkar, including Lakhvi, and ordered any of their U.S. assets to be frozen. Also named were Muhammad Saeed, the group's leader; Haji Muhammad Ashraf, its chief of finance; and Mahmoud Mohammad Ahmed Bahaziq, a financier with the group.
