The information on Badhwar Park, the landing site, was shared by ISI operatives with Pakistani-American Lashkar operative David Headley who had checked it out while conducting recce of the area, it says.
The book 'The Siege' by Adrian Levy and Cathy Scott-Clark claims that when Headley was subjected to undergo a two-year course on surveillance and counter-intelligence by Pakistan's espionage agency Inter-Services Intelligence (ISI).
His handler, Major Iqbal of ISI, gave him what he described as classified Indian files that he said had been obtained from within Indian police and army which revealed their training and limitations.
According to the book, before leaving Pakistan Headley met up with Major Iqbal who gave him a bundle of counterfeit Indian currency and a suggestion.
"Honey Bee, the ISI double agent, who had provided the classified Indian training manuals had come up with a potential landing area, in Badhwar Park, a fishing colony in South Mumbai, reporting that it was only patchily patrolled and was shielded from the road," the book claimed.
