Arriving in Chennai on Wednesday, a team of Delhi Police served a notice to AIADMK leader TTV Dinakaran for joining the probe in the case pertaining to the bribing of an Election Commission official for the 'two leaves' symbol.
The police had, on Tuesday, issued a lookout notice against Dinakaran.
The lookout notice was issued as it was feared that Dinakaran, being an NRI, could try to flee the country.
A Delhi Court had earlier on Monday sent Sukesh Chandrashekhar, the middleman alleged of striking a deal of Rs. 50 crore to help the AIADMK faction keep the 'two leaves' poll symbol, to eight-day long police custody.
The development came after the Crime Branch recovered approximately Rs. 1.3 crore and two luxury cars, a BMW and a Mercedes, from Chandrashekhar.
Dinakaran was also named as an accused in FIR filed by the Delhi Police Crime Branch for allegedly offering bribe for his party's 'two leaves' symbol.
Dinakaran's faction contested on the hat symbol after the Election Commission froze their two leaves symbol while acknowledging the split in the party.
Chandrasekhar was arrested from the Hyatt hotel on Sunday night and was produced at the residence of Special Judge Poonam Chaudhry who allowed the Delhi Police's plea to interrogate the accused for eight days.
The case pertained to an alleged attempt to bribe an Election Commission official by the AIADMK (Amma) leader for trying to get the party's poll symbol of 'two leaves' in a by-election to the R K Nagar Assembly seat in Tamil Nadu. The polling was later cancelled by the Election Commission.(ANI)
