Senior IAS officer Ashok Khemka, who had kicked up a political storm alleging irregularities in land deals involving businessman Robert Vadra and DLF, was today again transferred by Haryana government for the second time in nearly six months. While no reasons were cited in the statement, sources said that the whistle-blower bureaucrat had raised hackles over his decisions on postings and disciplinary action against employees of the Corporation. During his 21-year-long career, 47-year-old Khemka has been transferred over 40 times.
