Under pressure to crack the Gauri Lankesh murder case, the Karnataka Police special Investigation team had earlier revealed that they have identified the killers but remained short of naming them.
However, in yet another breakthrough the SIT on Saturday released the sketches of suspected killers and sought “public help”.
The probe team has also released a video of the suspects that they obtained during the investigation.
The sketches have been released based on CCTV footage obtained and, according to the investigators, the attackers were in the city for at least seven days before the murder and inspected Ms Lankesh’s house and the locality.
At least 250 people have been interrogated in connection with the case.
55 year old Gauri Lankesh was a well known critic of right-wing ideology and a fierce advocate of secularism and she was shot as she returned home early in September from her office in Bengaluru.
A man wearing a helmet to conceal his face was recorded on security cameras as he shot her in the chest.>
