Officials of the Central Bureau of Investigation (CBI) are carrying out a search at the residence of MK Stalin, son of DMK chief MK Karunanidhi, on Thursday.
Curiously, the search comes two days after the DMK announced its decision to pull out of the central government and the Congress-led United Progressive Alliance (UPA), dissatisfied with the centre's stand on the Sri Lankan Tamils issue.
The raid at Stalin's house began around 6 am. CBI officials here are tightlipped about the details of the case.
It is reliably learnt that the CBI registered the case in New Delhi and the raids are in connection with the import of cars and payment of customs duties.
The CBI also raided Stalin's friend Raja Shankar's house here in this connection.
Reacting to the raids, Stalin told reporters that it was mere political vendetta, and he would face all the legal cases.
Stalin is the third person in his family to be questioned by the CBI.
In 2011, the CBI questioned Stalin's mother Dayalu Ammal and sister Kanimozhi.
Kanimozhi and Dayalu Ammal were questioned in connection with the flow of over Rs200 crore from Swan Telecom promoter Shahid Balwa's DB Realty firm to Kalaignar TV, a regional Tamil channel in which Karunanidhi's family members allegedly have majority stake.
Later Kanimozhi was charged as co-conspirator in the 2G scam with former telecom minister A.Raja, and lodged in Tihar jail. She is now out on bail.
