Finance minister P Chidambaram said on Thursday that he strongly disapproved the CBI searching the residence of MK Stalin, son of DMK chief MK Karunanidhi, and added that it would send strong signals.
"Normally I do not comment on the working of another department (home ministry), but in this case I have to say that I strongly disapprove of the CBI's action. It is bound to be misunderstood," Chidambaram said.
"I have conveyed my views to the minister in charge and I suggest you put further questions to the minister in charge," he added.
Officials of the Central Bureau of Investigation (CBI) Thursday carried out a search at Stalin's residence in Chennai.
The search comes two days after the DMK announced its decision to pull out of the Congress-led United Progressive Alliance (UPA) over the central government's stand on the Sri Lankan Tamils issue.
The raid at Stalin's house began around 6am.
