According to India Today report, the Prime Minister Office (PMO) decided to re-evaluate the deployment of nearly 500 security personnel during his movement in the Capital. And a honest and brave police constable prompted the PMO to take this decision.
According to the report, Modi was shocked initially when he received a blunt reply from a Delhi Police Constable who brought the real picture while answering to Modi's question that why they did not keep their workplace (police station) clean.
Modi paid a surprise visit to Mandir Marg Police Station in Delhi on Oct 2 when he launched his Swachh Bharat mission. The Prime Minister himself took broom and cleaned the car parking area of the police station. During his interaction with the cops, Modi got to see the reality as the police constable informed him that the police station was not clean because "a majority of them (policemen) remained occupied with his security route and they just didn't have the time for anything else".
The India Today report also quoted a senior police official (on the condition of anonymity) as saying, "On Oct 3, a new set of guidelines for the security arrangements came from the PMO which clearly asked the Delhi Police to deploy only the required number of personnel for the prime minister's security instead of turning the city into a fortress."
