Nine CPI(M) workers were found guilty on Friday by a Kerala court in the murder case of Elambilayi Suraj, a BJP worker, in this district nearly two decades ago.
They were convicted by Thalassery Principal District and Sessions Court Judge K T Nisar Ahammed.
The quantum of punishment will be pronounced on Monday.
Among those found guilty is T K Rajeesh, who is already serving a prison sentence for his involvement in the T P Chandrasekharan murder case of 2012.
According to the prosecution, Suraj was murdered due to political rivalry after leaving the CPI(M) and joining the BJP.
Rajeesh and P M Manoraj were named in the case based on his statement to the police following the former's arrest in Mumbai in connection with the TP murder case.
According to the prosecution, on August 7, 2005, at 8.40 am, a group arrived in an autorickshaw in front of the Muzhappilangad telephone exchange and hacked Suraj to death.
