The protesters expressed concern and asked how come taxpayer's money was spent on policemen following the woman around on flights, in hotels and malls, and how her phone was illegally tapped.
Two investigative portals, Cobrapost and Gulail, had claimed on November 15 that Amit Shah, former Home Minister of Gujarat and Narendra Modi's close aide, had ordered illegal surveillance of a woman at the behest of one "saheb".
They had released taped conversation between Shah and an IPS officer to back up their claim.
BJP rejected the charge saying the woman has not lodged any complaint.
