The manager, Natarajan, was looking after affairs of the estate and also reportedly the Green Tea Estate, a few kilometres away from Kodanadu, which was brought by Jayalalithaa and Sasikala five years ago.
After having carried out the searches in both the estates since November 9, the officials brought Natarajan here yesterday.
A group of officials today questioned Natarajan reportedly for nearly six hours from morning, police sources said.
