Police personnel were posted at the Nungambakkam residence of P Chidambaram following an ED raid.
Five properties belonging to the family, including the ones in Chennai, Delhi and Karaikudi, were subjected to the sudden search operations by the CBI and ED.
He also said this was not an enquiry but just a raid, and kept emphasising that nothing was found or seized.
"The officers told me that they thought Karti is an occupant of this house, but he is not", he added.
"It was a raid conducted under the provisions of PMLA", said Arun Natrajan.
ED had provided information about the alleged illegal payments made by INX Media and consequentially Central Bureau of Investigation (CBI) had registered FIR. The agency had conducted similar raids on the properties belonging to the family on 1 December past year.
"They found nothing in the Chennai searches".
He has been asked to appear by the agency on January 16 in this case.
The Congress, too, was critical of the action against its senior leader and termed the ED raids "a malicious vendetta" by PM Narendra Modi and his government against senior Congress leaders.
Chidambaram also said he had yesterday itself anticipated that as the notices were issued by the SC, "the ED has to conduct some drama in order to cover up some track and hence will conduct searches in Chennai".
The Airtel-Maxis case was part of the wider 2G scam that engulfed the UPA regime.
In 2011, former Aircel head C Sivasankaran complained to the CBI that he was being forced by then telecom minister Dayanidhi Maran to sell Aircel to the Malaysia-based Maxis Communications group owned by T Ananda Krishnan. ED had also carried out raids in the premises of Karti's relatives and others on December 1, 2017.
It was alleged that Karti received Rs 3.5 crore for assisting INX media in getting FIPB approval.
