Suraj Pancholi, 22, son of actor Aditya Pancholi, was produced before the Andheri magistrate after the expiry of his judicial custody in the morning.
At the hearing, the police prosecutor opposed Suraj's bail plea on grounds that the probe into Jiah's case was at a critical state and his release on bail could hamper investigations.
On Wednesday, Suraj had moved the Bombay High Court for bail after his earlier bail pleas were rejected both by the magistrate court and the Sessions Court.
He will continue to be lodged in the Arthur Road Central Jail till his bail plea comes up.
On June 3, Jiah, 25, was found hanging in her flat in Juhu area here.
Suraj was nabbed after a note written by Jiah blamed him for the suicide.
