Chandra arrived at the Crime Branch office in Chanakyapuri at 2 pm while son Puneet Goenka reached there at 2:30 pm along with their lawyers. The questioning went on till late in the night.
Zee editors Sudhir Chaudhury and Samir Ahluwalia were brought to the crime branch office while Chandra and his son were being questioned.
Chandra had secured a interim protection from arrest till December 14 by a Delhi court. Chaudhury and Ahluwalia were remanded in police custody for two days by a Delhi court today.
Chandra's questioning came following police sending three notices to him asking him to join investigations in the case in which Chaudhury and Ahluwalia were arrested late last month following investigations into complaint filed on October 2.
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 today.
Investigators have told a local court earlier that they were treating Chandra as an accused as he knew about the dealings between his employees and Jindal's company.
Zee Group has denied the allegations of extortion and demanded the immediate release of its two senior journalists, alleging the police action was "illegal" and "designed for something else".
