An ambulance was briefly stopped, so were other vehicles in Tamil Nadu's Kumbakonam, about 293 km from Chennai, on Monday to allow a convoy of a state minister.
A video showing the ambulance with the sirens blaring and being halted by a police constable went viral on social media.
The constable was seen saluting the vehicle in which State School Education Minister Anbil Mahesh Poyyamozhi was reportedly travelling.
More than a dozen vehicles were in the convoy and the ambulance was made to wait a few minutes till the convoy passed.
When contacted, a senior police official in Kumbakonam claimed the scope of halting an ambulance to provide a quick passage to the minister's convoy was remote.
he functionaries of the Opposition AIADMK criticised the ruling DMK by citing the video.
