Any statement or confession recorded by a metropolitan or judicial magistrate under section 164 of CrPC is admissible as evidence in a court.

The crime branch officer said the four would be called after court gives a date for recording their statements.

Meanwhile, Judicial Magistrate Kshama Joshi today rejected Tejpal's application for a fan in the lock up where he is in police custody since Saturday.

On December 2, Tejpal's lawyer had petitioned the court for a fan to be installed in the lock up on humanitarian ground.

A woman journalist of Tehelka, who later resigned, has accused Tejpal of sexually assaulting her twice on November 7 and 8 in Goa. Tejpal has been booked under Sections 354A (outraging the modesty of a woman) and 376 (2)(K) (custodial rape) of IPC.
