A court here on Wednesday sent sidelined AIADMK leader T.T.V. Dinakaran, arrested on the charge of attempting to bribe Election Commission officials, to five-day police custody.

Special Judge Poonam Chaudhary allowed the Crime Branch to quiz Dinakaran, a nephew of jailed AIADMK party chief V.K. Sasikala, for five days after the Delhi Police sought his custody to unearth the entire conspiracy.

Dinakaran was arrested on Tuesday night by the Delhi Police Crime Branch for trying to pay out Rs 50 crore in bribes to the poll officials through middleman Sukesh Chandrasekar to ensure the 'two leaves' poll symbol was allotted to the AIADMK faction led Sasikala.
