Jayarajan was arrested in the case but was later released on conditional bail.According to CBI investigation, the murder of Manoj which was executed on September 1, 2014, was a well-conspired, planned and well-organized political murder and it is not an individual instance under sudden provocation against Manoj. His father, late Chathukutty and his family members were having good acquaintances with P Jayarajan and members/sympathizers of the CPI(M).After the death of Manoj’s father, he developed acquaintances with RSS members and this was disliked by Jayarajan. In 1997, Manoj switched his political affiliations to join the RSS. P Jayarajan, who was the local leader of CPI-M warned Manoj to leave RSS and to join back CPI(M). He also warned his brother and mother of dire consequence in this issue, the investigation revealed.Since 1997, Manoj became a political target of Jayarajan and attempts were made to eliminate him through his close associates. There were attempts on his life twice, each in 1997 and 2009. Later in 1999, Jayarajan was attacked and Manoj was one of the accused in the case.According to the investigators, the new BJP government came to power in the centre, in June/July 2014, there was a considerable migration of CPM worker to BJP and RSS and it was weakening the CPI (M) in the Kannur district and there was gain in strength to the BJP, investigations revealed.Meanwhile, a function was organized on 24th August, 2014 to receive about 500 CPM party workers to BJP at Navaneetham Auditorium, Kannur.“It was the need of the hour for the CPI (M) to contain and boost the morale of the CPI-M party workers in Kannur District and to prevent them from deserting the party. At this juncture, P Jayarajan wanted to eliminate the upcoming and influential district level leader of RSS who was a botheration for Jayarajan, personally and politically,” said a source with the CBI.P Jayarajan who is the principal conspirator had entered into criminal conspiracy with Vikraman and used him to execute the killing by organising professional killers, lethal weapons and bombs in the field level, sleuths said.Vikaraman with the help of P Jayarajan, could gather outsiders-Nithin, Siraj, Jagga Rzahim, Prabhakran who are from different areas for assistance. He was not able to arrange them in his personal capacity.SIM cards, weapons and explosives were arranged with the assistance of other accused persons.With explosives and weapons, Vikaraman and 16 others assembled at Paraikavu the ancestral temple of P Jayarajan from August 26, 27 and 29, 2014 to take position and attack Manoj. On August 29, 30 and on September 1, 2014 Vikaraman and his gang members changed their location of assembly to a house under construction of Rijesh at Pattuvathu Valavu, Ukka Motta.On the day of the murder, the accused persons inflicted maximum injuries on the vital parts of the body. When the victim was close to death, Nijith with a steel dagger, slit the throat of Manoj to ensure his death.Investigations found that Jayarajan further conspired with close associates C Prakash, Krishnan Arappayil, Ramachandran, Madhusudhanan and Rijesh to provide treatment to Vikraman who got injuries during bomb explosion and to harbor him.
