With farmers gearing up to block the highway and picket toll plazas on the border to Delhi on Saturday in response to a call from protesting farmer unions to intensify their agitation against the three agricultural sector laws, police personnel have been deployed in strength to protect toll booths and ensure smooth flow of traffic, Faridabad Police said.

As many as 3,500 police personnel will be deployed at the five toll plazas in the area, a statement said.
