Surveillance/Phone records Pramod Lele, December 2003

According to the June 2003 surveillance strategy, Mr. Handa was requested to approve a plan which included obtaining confidential and personal bank account information for Dinesh Lakhani, the Parke-Davis shareholder who sued Parke-Davis over the terms of Pfizer's acquisition of that company.
The document also lists need for phone records, even bribes are openly discussed.
Additionally, the report makes clear that an office assistant working for Trent Ltd. is available as an in-house spy.
The first set of document have Pfizer's Company Secretary A. Anjeneyan's handwriting and recommendation to Handa (Anjeneyan reported to Handa and has since left the company).
According to the surveillance reports, Pfizer also spied on Shreeharsha Vasant Phene, who at the time was a corporate planning vice president of Trent Ltd, which owns supermarkets and retail stores, and belongs to the TATA group (more here).
Mr. Idnani comments: "Why Pfizer and Handa ordered this surveillance, I cannot fathom. It is possible the Pfizer India people were taking advantage of the situation to settle personal scores or even to harm and blackmail them."
Pramod Lele, one of the targets for Pfizer's investigations, had been the country manager of Warner-Lambert (Parke-Davis) in India, and had started reporting to Pfizer N.Y where the merger had already taken place.
According to Idnani, he had been promised that he would become the Pfizer India managing director of the merged company.
