Two vehicles of Assam agriculture minister Pramila Rani Brahma collided at Hatigaon area on Monday and an auto-van driver was beaten up for not giving them the way in time.
Official sources said the two vehicles of the minister's convoy collided in front of a school when the auto-van failed to move away when signalled by the drivers.
After the collission, Brahma's bodyguard alighted from the minister's car and assulted the auto-van driver for not moving away in time and damaged his vehicle, eye witnesses said.
Following this, angry locals blocked the road and detained the bodyguard demanding that the minister apologise for her staff's violence.
The blockade was lifted after the police intervened and the auto-van driver was provided medical assistance.
