The Bharatiya Janata Party workers protested outside Delhi Chief Minister Arvind Kejriwal's residence today over the Aam Aadmi Party allegedly procuring 'snooping' equipment.

The police used water canons to quell the protests leaving one protester injured. 

"The AAP wants to break into people's privacy. Who gave them the right to tap Delhi people's phone calls," asked BJP's Delhi unit chief Satish Upadhyay.

"We will protest against this wherever possible. Who gave Arvind Kejriwal permission to buy snooping equipment?"

The Kejriwal-led government has triggered another controversy after it turned out it was considering buying high-end equipment for surveillance and monitoring for its anti-corruption branch. The plan to buy the equipment for "research, analysis, surveillance and monitoring purposes" was part of a Rs 36-crore proposal to run the ACB, up from Rs 7 crore spent on it currently, The Hindustan Times reported.

A cabinet note prepared for the Kejriwal cabinet proposes to spend Rs 3.2 crore on the high-end equipment  and the rest on vehicles, mobile phones, computers and salaries for additional staff, according to the report.
