ASK condemns brutal killing of Niladri Chattopadhyay Nil at his residence by unknown killers. But the pattern of killing suggests that Niladri was killed by the same group informed in killing on Avijit, Wasiqur and Ananta. ASK is appalled at the state of affairs which gives reasons to believe that the law enforcement agencies are not acting seriously enough to stop such violence on the free thinkers. ASK demands immediate independent investigation of the killing of Niladri and bring the perpetrates to accountability. ASK also urges the government to take all necessary steps to end all kinds of violence by the militant forces.
