Chandigarh, Oct. 11 -- The Chandigarh police on Friday set up a six-member special investigation team (SIT) to ensure a "prompt, impartial and thorough investigation" into the alleged suicide of Haryana IGP Y Puran Kumar, who was found dead at his residence on October 7.

A day after police registered an FIR against 11 senior officials for abetting IGP's suicide, his wife and senior IAS officer Amneet P Kumar accused UT police of invoking "weaker" sections of the SC/ST (Prevention of Atrocities) Act.
