Investigating agencies had later denied this possibility and stated that Kasab and the other nine terrorists had no local help.
The investigation, currently being conducted by the National Investigation Agency, has highlighted the possibility that David Headley -- the American citizen arrested last month in Chicago by the Federal Bureau of Investigation on terror charges -- may have involved a couple of women in his plans.
Sources told rediff.com that Headley, during his eight visits to India, was often seen in the company of women as he travelled across the country. The Intelligence Bureau says they have information that at least a couple of these women were aware of his plans.
Among the several women Headley was seen with, the IB sources say two in particular could have guided Kasab and Khan on that horrific night.
Investigators say the initial part of the attacks was extremely crucial for the Lashkar-e-Tayiba since it gave the other terrorists time to gather undetected at their respective targets.
Once the murderous mayhem at the CST commenced, the terrorists's Pakistan-based handlers directed the other killers over satellite phones, the records of which are with the Mumbai police.
NIA agents, who have visited hotels that Headley stayed in, have confirmation that Headley was often seen with women. The agency has collected information on the appearance of these women and are in the process of identifying them.
Sources said Headley also contacted escort services in India; one such location in Mumbai has provided investigators with information.
