Chennai, March 11 (IANS) DMK MP and Tamil Nadu Chief Minister M. Karunanidhi's daughter Kanimozhi was Friday being questioned by the Central Bureau of Investigation (CBI) in connection with the allotment of 2G spectrum licences.

Karunanidhi's second wife Dayalu Ammal and senior official in Kalaignar TV Amrathan, who is close to the family, will also be questioned, officials said. The interrogation is going on in the Kalaignar TV office at the DMK headquarters here. The three arrived at the office around 10.20 a.m.

Officials said they would be questioned in connection with the flow of over Rs.200 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 a majority stake.

While Kanimozhi is said to have 20 percent stake in the TV channel, Dayalu Amma has 60 percent stake. The balance 20 percent is with Kalaignar TV managing director Sharat Kumar, it is learnt.

Balwa is one of the accused in the scam and his Swan Telecom was allegedly favoured by former communications minister and DMK MP Andimuthu Raja in the allocation of second generation (2G) spectrum licences.

CBI is probing if there was any quid pro quo under which Balwa transferred funds to the TV channel and in return got 2G spectrum licences at throwaway prices, sources said.

Balwa and Raja are amongst the four people in jail in connection with the corruption scandal that is said to have cost the exchequer massive losses.
