The Valasaravakkam police have registered a case against film director and leader of the 'Nam Tamizhar Iyakkam' Seeman in connection with the attack on the house of actor Jayaram on Friday.
According to the police, Mr. Seeman was accused of instigating the attack on the actor, who allegedly made derogatory remarks on a Tamil woman in a recent interview.
While eight persons were held soon after the attack on Friday, a special team investigating the case arrested four more on Saturday, including Seeman's brother James Peter.
Mr. Jayaram's house in Lakshmi Nagar was damaged after a group of youths threw stones and set on fire furniture at the main entrance. Valasaravakkam Inspector Murugesan and Sub-Inspector Rajaram were shifted out for not taking action to prevent the attack despite intelligence inputs.
Additional armed police personnel have been deployed at the house of the actor, sources said.
Chief Minister M. Karunanidhi on Saturday said as actor Jayaram had expressed unconditional apology for his remarks, it would be better to forgive him and leave the matter at that.
Replying to a question, he said if the actor had spoken anything derogatory of Tamil women, it needed to be condemned. But, as he had offered an unconditional apology, it would be better to follow what former Chief Minister C.N.Annadurai had said" "Let us forget and forgive."
He said the police could not remain spectators to acts of intimidating the actor's family members and setting fire to his house.
