Controversial IAS officer Puja Khedkar on Thursday took charge as an assistant collector at the Washim District Collectorate in Vidarbha region, but declined to comment on the flurry of claims that she used illegal means to clear her civil services exam. Khedkar (32), who has been accused of allegedly misusing benefits under the physical disabilities category and other backward class (OBC) quota to secure a position in the Indian Administrative Services, was transferred on Monday to Washim from Pune over allegations of bullying and entitled behaviour.
