Seven DMK local functionaries were arrested here today for leading a demonstration seeking a detailed inquiry into the unearthing of a unit manufacturing banned tobacco products like gutka and paan masala, police said.
Leaders, including former president of Kannampalayam panchayat Murugesan, were held for holding the protest in front of the unit without permission, they said.
Police said they were searching for DMK MLA N Karthik, who also participated in the protest during which the agitators alleged that the ruling AIADMK was "attempting to hush up the case."
