The ISI officials periodically checked on Laden also, this sensational disclosure has been by Chuck Pfarrer, a former SEALs, in his latest book "Seal Target Geronimo" that hit the stands here today.
Pfarrer says his account in the book, that gives a blow by blow account of the killing of bin Laden in a surprise US raid in Abbottabad on May 2, is based on his interviews and interaction with members of the SEALs team that killed Laden and the US military and Obama Administration officials.
All the sources have been kept anonymous.
Notably officials of the Obama Administration, Department of Defence and Central Intelligence Agency (CIA) have so far maintained that they haven't obtained any evidence which indicates about the ISI knowledge of the whereabouts of Laden or providing support infrastructure to him.
"The ISI knew exactly where he was, but did not inform the US. They continued to let Osama pace back and forth in his compound," Pfarrer wrote in his 225-page book published by New York-based St Martin's Press.
Giving an insight into the last few months of Laden's life, Pfarrer wrote that he became increasingly reclusive and seldom left the main building, unless it was to put on a set of golden-threaded robes and have one of his aides film him as he tried to read pronouncements to be aired on Al Jazeera or released on al-Qaeda's web sites.
