Pancholi, 22, son of actor couple Aditya Pancholi and Zarina Wahab, was produced before the Andheir magistrate after the expiry of his judicial custody in the morning.
At the hearing, the police prosecutor opposed Sooraj'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, Sooraj 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.
Sooraj was nabbed after a note written by Jiah blamed him for the suicide.
