Maximum period of Police remand of an Accused is?

Under Section 187(2) BNSS (formerly s.167(2) CrPC) a Magistrate may authorise detention of an accused in police custody for not more than fifteen days in the whole, which may be taken in whole or in parts at any time during the initial forty or sixty days of the detention period; the rest of the detention, up to 60 or 90 days in total depending on the offence (Section 187(3)), must be judicial custody. This relaxes the rule in CBI v Anupam J. Kulkarni (1992), where the Supreme Court held that police custody could be given only within the first fifteen days of remand.
