New Delhi: Former BJP leader Dayashankar Singh, whose abusive remarks against BSP chief Mayawati caused an outcry, was arrested on Friday in Bihar after being on the run for days, police said. Additional Superintendent of Police Keshav Yadav said on telephone from Buxar that a joint team of the Uttar Pradesh Special Task Force (STF) and Bihar Police nabbed him from Chini Mill area in Buxar. "He will be taken to Uttar Pradesh," Yadav said, adding it was being investigated when he reached Bihar and with who he was staying. A non-bailable warrant had been issued against Dayashankar Singh, a Bharatiya Janata Party leader from Uttar Pradesh who on July 19 made the remarks against Mayawati at Mau in the state. A case was registered the next day and the BJP expelled him. He had been on the run since then.
