The Central Bureau of Investigation has questioned Pattali Makkal Katchi founder S Ramadoss and his son, former Union Minister Anbumani Ramadoss, in connection with the murder of a relative of Tamil Nadu minister for Commercial taxes C Ve Shanmugam, sources said.
While the senior PMK leader was questioned last evening, Anbumani was interrogated few days ago, they said.
A relative of Shanmugam, Muruganandham, was murdered by an armed gang on May 8, 2006, when they tried to attack the former at his house in Tindivanam.
Muruganandham died while trying to save the life of Shanmugam, All India Anna Dravida Munetra Kazhagam strongman in Villupuram district. The attack was following political enmity between Shanmugam and PMK.
