A police team investigating the murder of Rashtriya Swayamsevak Sangh worker A. Sanjith arrested one more suspect on Wednesday.
He was remanded in judicial custody for two weeks. The police said he drove the car that carried the assailants.
The investigation team may move the court for his custody on Thursday. Another person, who was arrested on Monday, was sent to police custody for five days as part of the investigation. Police said he was the one who hacked Sanjith first.
Sources said almost all the culprits involved in the murder were rounded up from different places.
However, police registered the arrest of only two of them.
Registering the arrest of all the accused at the same time is likely to cause a lot of inconvenience for the investigating team.
Police said all the arrested were Popular Front of India (PFI) workers. The police are yet to reveal the details of the accused.
Car parts found
Meanwhile, the police team found the scrapped parts of a car allegedly used by the assailants.
The car, suspected to have been scrapped as part of a move by the assailants to destroy evidence, was found in a workshop at Pollachi in Tamil Nadu.
The vehicle had developed mechanical fault while the attackers were returning after the murder.
The police said it was taken to Pollachi and scrapped in a workshop there after getting it repaired here.
Fake number plate
The assailants had used a fake number plate, police said.
Sanjith was hacked to death by a gang when he was travelling on a bike along with his wife at Mambaram, near here, on November 15.
