Barwani: The police registered an FIR against 400 unidentified persons who attacked police and a Sub Divisional Magistrate (SDM) on Sunday, officials said.
Around 7,000 migrant workers blocked Agra-Bombay Road in Bijasan in MP's Barwani -- a red zone area -- on Sunday and allegedly pelted stones at the police, injuring the additional SP, an SDM and three other police personnel.
The migrants were angry at being blocked on the Maharashtra-MP border and demanded to be allowed to pass through MP on their way to UP, Bihar, Rajasthan and Odisha.
For the last two days, they were pressurising the Barwani administration to let them through, and squatted on Agra-Mumbai NH a few times, but were persuaded to call off the protest.
