A court in New Delhi on Thursday asked AIADMK leader TTV Dhinakaran, accused of attempting to bribe Election Commission officials, to file a reply on a Delhi Police plea seeking his voice sample.
Special Judge Poonam Chaudhary directed Dhinakaran and his aide Sukesh Chandrashekhar to file their reply and fixed May 15 as the next date of hearing.
Delhi Police have sought the court's permission to get Dhinakaran and Chandrashekhar's voice samples to authenticate a recorded conversation that took place between the accused.
The court also extended the judicial custody of Chandrashekhar till May 15.
Dhinakaran, nephew of jailed AIADMK General Secretary VK Sasikala, is currently in judicial custody till May 15 over the bribery allegations.
Dhinakaran is accused of having tried to obtain a favourable verdict from the poll panel so that the now frozen "two leaves" party symbol could be restored to Sasikala's faction of the AIADMK.
Chandrashekhar was arrested on April 16.
On April 25, the Delhi Police Crime Branch arrested Dhinakaran for having tried to pay Rs 50 crore in bribes to the poll officials through middleman Chandrashekar to ensure the "two leaves" poll symbol was allotted to the AIADMK faction led by Sasikala.
Mallikarjuna, a long-time friend of Dhinakaran, and a hawala operator from Delhi, Naresh Jain, are also in judicial custody.
