The brothers had been charged with conspiring with the chairman to amass wealth to the tune of Rs 8.23 crore.
CBI and local police sources said they could not trace Vaikuntarajan in his native place near here or in Chennai and suspected he might be absconding to get ready to file an appeal in the Supreme Court.
On Nov 7, the Madurai bench had dismissed the bail plea of the brothers,who apprehended arrest by CBI in the wealth case.
Subbiah had been charged with amassing assets and pecuniary resources of about Rs.8.23 crore in conspiracy with his mother under the guise of selling property in Karisalkulam village in Virudhunagar district in 2011 to the brothers.
The brothers had been charged with paying the amount to Subbiah under the guise of returning the advance for buying the property for a sum very much higher than its market value.
They maintained the charge interlinking them with Subbiah was not true and had sought anticipatory bail.
