Sreejeev's brother, Sreejith, has been protesting to seek justice for the last 767 days outside the Secretariat in Thiruvananthapuram.
"Will continue my protest till the CBI probe begins, will also consult legal experts," Sreejith said.
The letter in this regard was sent on January 13 by the state chief secretary asking the CBI to re-examine its earlier decision not to take up the case.
However, the plea was rejected by CBI stating they had an overload of cases and this particular incident did not come under the rarest of rare cases, the release stated.
Sreejeev, died at a Thiruvananthapuram hospital on March 21, 2014, allegedly due to police torture. He was taken into custody in an alleged case of theft. (ANI)
