Bathinda, Oct. 15 -- Hours after anti-drug activist Parvinder Singh, alias Jhota, was shot dead in Mansa, the police on Wednesday arrested the accused, a pharmacy owner, from Rajasthan even as anger against the killing spilled onto the streets, with mob setting the chemist's shop ablaze and authorities razing a portion of his house.
