KOLKATA, Dec 30: Demanding that “outsiders” immediately leave the villages in the area and arguing in favour of overall development, the Trimool Congress on Saturday held a ‘Peace rally’ in West Bengal’s Bhangar that has witnessed violence over the construction of a power grid substation. The development comes two days after several people were injured and vehicles set ablaze in a clash between a group of protesters agitating against the power grid project and Trimool Congress activists on Thursday.
