Since Kamaraj met the prisoners who were arrested in the case for plot a case for plot was filed against him in 1933.

Police tried to include the name of Kamaraj in the case of Composite State Plot under the name of Chennai Plot. Police pleaded that Kamaraj , Arunachalam and others tried to shoot Sir John Anderson , Governor of Bengal who was staying at Ooty  , and for that Kamaraj gave 2 revolvers to Arunachalam. Since this case failed they filed another case of Plot against him. It was Bomb blast at Srivilliputhur - Virudhunagar  Police station.

In this case K.S.Muthusamy was accused , Kamaraj the second and Reporter Marriappan as third accused. Narayanasami as fourth accused. Venkatachalam turned as approver .

At Virudhunagar Bombay show was conducted . Muthusami was in that show upto night 2'o clock along with the Sub-Inspector of Police Mr.Anantha Ramakrishnan. Only on that night Bomb throw case was fabricated.

A C.I.D. Inspector by name Thothari Iyengar came from Madras to fabricate this false case The Sub-Inspector Anantha Ramakrishnan was instructed to five false witness. But he refused. Hence he was transferred to some other place. D.S.P. , Sivakasi  , Parthasarathy Iyengar ( Later he was the I.G. of Madras State ) took active part in fabricating the case.
