Delhi chief minister Arvind Kejriwal on Wednesday waded into the debate over the lynching of a man in Bisada village of Uttar Pradesh over rumours that he slaughtered a cow, hitting out at “poisonous” politicians for instigating riots and flaring tensions. In a radio spot, an audio clip of which was circulated by the Aam Aadmi Party (AAP), Kejriwal is heard criticising political parties for the lynching of 55-year-old Mohammed Ikhlaq by a mob on September 28. He did not name any political party.
