Chandra had earlier told police that he could not appear before them as he was out of the country but later on December 3 he told them he will be ready to appear within 96 hours of notice. Police then asked him to appear before them on December 8.
Investigators have told a local court earlier that they were treating him as an accused as he knew about the dealings between his employees and Congress MP Naveen Jindal's company.
Zee Group has denied the allegations and demanded the immediate release of its two senior journalists, alleging the police action was "illegal" and "designed for something else".

Terming the campaign as "vicious", "malafide" and "unwarranted", the letter said Chandra had informed the police on November 27 that he went ahead with his "pre-scheduled" meetings and engagements in India and abroad.
While granting interim relief from arrest, the court had directed Chandra and his son to "join and cooperate" with the probe. It had ordered both of them to surrender their passport with the police.
