Agitation against toll collection on nine roads in Kolhapur city in western Maharashtra on Sunday took a violent turn with suspected Shiv Sena activists vandalising four toll booths.
Police said they have detained some of the protesters who vandalised the booths.
Shiv Sena workers are being blamed for the attack.
There is no report of anybody having been injured during the attack on booths, police said.
Some protesters vandalised the office of IRB Infrastructure Developers, a private company, which manages the toll booths on nine roads leading to the city.
City residents have been agitating against the toll collection on these roads for the last three years.
About dozen members of anti-toll action committee had launched a hunger strike six days ago, saying that they would not call it off unless the toll collection stopped.
Maharashtra Minister of State for Home Satej Patil and Labour Minister Hasan Mushrif had reportedly met the activists yesterday and assured them that government would ask the company to stop the toll collection.
However, the collection continued at the booths this morning, which led to the violence.
