On March 9, six months after the murder of Gauri Lankesh, the Karnataka police arrested alleged gunrunner Naveen Kumar who was taken into police custody on March 2 for interrogation in connection with the case.
The same day, a Bengaluru court gave the SIT of the Karnataka police five-day additional custody of the accused.
Naveen Kumar's family has maintained that he was innocent and in no way connected to the crime.
Gauri Lankesh, 55, was known as an anti-establishment voice with strident anti-right wing views, and was shot dead at close range by unknown assailants at her home in Bengaluru on September 5 last year.
The killing of the journalist had drawn widespread condemnation and the Siddaramaiah government had come under flak for not making any headway in nabbing the culprits.
