It is, however, not known when Dhinakaran has been asked to appear before them.
Assistant Commissioner Sanjay and another official served the summons to Dhinakaran at his upscale Besant Nagar residence here.
The Delhi Police personnel, who were inside Dhinakaran's house for about 20 minutes, declined to speak to the waiting media while leaving the premises.
Anxiety and tension, meanwhile, prevailed for a while as a party worker tried to allegedly set himself ablaze to show his opposition to the police.
The self-immolation bid was thwarted by other cadres and some plainclothesmen.
Dhinakaran had, soon after the arrest of Sukesh Chandrasekhar asserted that he will face the matter legally.
He had denied any knowledge of Chandrasekhar.
Yesterday, Delhi Police had issued a lookout notice against the Dhinakaran.
The lookout notice was issued in the wake of inputs that Dhinakaran was an NRI and could try to flee the country, police said.
The AIADMK (Amma) Deputy General Secretary is already facing the heat as the K Palaniswami Cabinet revolted against him last night and decided to keep him and his family out of the party and the government. Dhinakaran has convened a meeting of party MLAs in Chennai today.
Dhinakaran today virtually questioned the need for the lookout notice, saying how could he flee the country when his passport was "in court" for 20 years.
