Hours after ransacking the public works department office in Navi Mumbai, workers from Raj Thackeray’s Maharashtra Navnirman Sena (MNS) damaged the pavement outside Mantralaya in south Mumbai as a protest against the poor condition of roads across Maharashtra. The Marine Drive police have arrested six MNS workers for digging up the concrete tiles used to lay the pavement with pick axes and hammers, and throwing the debris on the road, around 3am on Tuesday.
