Thirty-three MPs have written to Home Minister Rajnath Singh, saying the "selective targeting" of persons should end.
The signatories to the petition, including Sitaram Yechury, D Raja, Mohd Salim, Ram Gopal Yadav and K C Tyagi, said targeting of Setalvad is a "vindicative attempt" to silence the voice of justice for the Gujarat riot victims.
The MPs from both Houses urged the Home Minister to "refrain from selective targeting of persons" as such attempts "have the potential of terrorising people into silence as they will believe they too will suffer the same fate if they dare to raise their voice against injustice".
