Following inputs, a search operation was launched in the office block and a room used by jailed and deposed AIADMK leader V K Sasikala at "Veda Nilayam," the Poes Garden residence.
"We have not searched the entire Poes Garden premises. Our team went at 9 pm and only Poongundran's room, records room and other room used by Sasikala were searched," the top Income Tax official told PTI.
Poongundran had served as an aide of the former chief minister.
Today's search comes days after multi-city searches in 187 locations linked to ten income tax assesse groups which include those linked to Sasikala, her kin and some associates.
