Congress president Sonia Gandhi on Monday wrote a letter to IAS officer D.K. Ravi's wife assuring her of a fair probe in the death case of her husband.
Karanataka Chief Minister Siddaramaiah is likely to order a CBI probe into the death case today.
Earlier on Saturday, Karnataka Pradesh Congress president G Parameshwara had requested Siddaramaiah to order a CBI inquiry into the case and had said that the truth in this matter should come to the fore without any confusion.
Siddaramaiah is believed to have decided to refer the IAS officer's death probe to the CBI after Sonia Gandhi advised him to do the same.
The IAS officer, posted as Joint Commissioner in Commercial Tax Department, was found hanging from a ceiling fan in his apartment by his wife on March 16. The police suspect it to be a case of suicide, though no note was found from around the officer's body.
The state government, which ordered a probe by the Criminal Investigation Department (CID) in the case, has so far ruled out a CBI inquiry.
