Two AIADMK functionaries, including local students wing union secretary Satheesh, were today arrested for allegedly throwing petrol bombs at a Congress Trade Union office at Chinnakalayamputhur in this district, police said.
Police said some unidentified persons cut the party's flagpost and also ransacked the office after breaking open the door by hurling petrol bombs around 2 am.
Police are on the lookout for four others in connection with the case.
AIADMK workers have been staging protests condemning TNCC chief E V K S Elangovan's alleged remarks against Chief Minister Jayalalithaa.
