Kolkata: BJP MP Arjun Singh suffered head wounds on Sunday after police cracked down on party workers who set up a highway blockade in Kankinara, North 24 Parganas district of West Bengal. Arjun Singh, seen in a blood-soaked shirt and a bandage, stated that he and his party colleagues were protesting against the "capture" of a BJP office by the Barrackpore Police Commissioner. "They attacked me and vandalised my car even though we were only protesting peacefully. Police Commissioner Manoj Verma hit me on my head, causing a deep wound. My residence is also being attacked,"  Singh said. However, a senior police officer said that the politician was hit by a stone thrown during a clash between two groups in Kankinara.
