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.
