Gurunath Meiyappan, son-in-law of BCCI chief N Srinivasan, was produced before the magistrate's court in Mumbai at 1pm on Saturday.
He was brought to the court premises in a white Scorpio of the Mumbai Crime Branch and was kept away from media persons, whose entry to the court and commissioner's office was restricted on Saturday.
Meiyappan, dressed in a navy blue Chennai Super Kings t-shirt, jeans and a pair of floaters, looked unperturbed and kept looking curiously at the court proceedings of other persons.
He chatted around with other people and wore a smile on his face as he waited his turn in the court.
Meiyappan was placed under arrest at 11.55 pm on Friday night, after the Mumbai crime branch questioned him for close to three hours.
Crime branch sources said, Meiyappan was questioned through the night and was also confronted with Vindoo following which he accepted his role in cricket betting.
Meiyappan used to place bets through the book 'Jack' that Vindoo operated, said crime branch sources.
A model who is being questioned has claimed that Meiyappan had told her during a phone conversation about how tense he was after losing Rs 10 lakh that he placed as a bet on CSK.
