All India Anna Dravida Munnetra Kazhagam (AIADMK) deputy general secretary T.T.V. Dinakaran on Saturday left from Chennai and headed towards Delhi, where he will appear before the police in connection to his alleged involvement in 'two leaves symbol' case. At the airport, the AIADMK leader refused to comment and said that he will speak to the media on returning back. Earlier on Thursday, a team of the Delhi Police Crime Branch reached Chennai and served a notice, asking him to join the probe. Dinakaran's faction were allotted 'hat' symbol for the R.K. Nagar assembly by-polls, after the Election Commission froze their two leaves symbol while acknowledging the split in the party. The polling was later cancelled by the Election Commission.
