A team of investigators attached with the Delhi police swooped down at the Chennai residence of AIADMK (Amma) leader TTV Dinakaran on Thursday evening. The Delhi police also had brought Dinakaran along to his Adyar residence. The team reportedly also questioned his wife Anuradha on their source of income.

According to sources, Dinakaran will also be brought to Bengaluru for further investigation. The scope of investigation might also extend to Kochi.

While a team of Delhi police are questioning TTV and his wife, another team of investigators along with Intelligence Bureau (IB) officials have landed at a luxury hotel in Old Mahabalipuram Road (OMR) to inspect CCTV footages from its premises. The team is expected to head back to Delhi on Friday.

TTV was arrested on Tuesday night in connection with an Election Commission bribery case and by the court order was remanded to five-day police custody. TTV will be in police custody till May 1. Mallikarjuna, a long time friend of Dinakaran who was arrested along with TTV, has also been remanded to police custody for five days.

Earlier last week, the AIADMK (Amma) leader confessed to meeting Sukesh Chandrasekar. During the course of interrogation and sustained quizzing, TTV allegedly told the investigators that he did meet Suresh, who had posed as a high court judge and sought to help him in the matter, police sources said.

Dinakaran, who is accused of trying to bribe an Election Commission official in a bid to retain the 'two leaves' symbol of AIADMK, however, maintained that he did not pay any money to Sukesh in this regard, police said.

A resident of Bengaluru, Sukesh studied at Bishop Cotton School on Residency Road. There are 15 FIRs and over 100 complaints of extortion in Bengaluru, Chennai and Hyderabad against Sukesh.
