24 hours after the Delhi High Court allowed their bail, student-activists Natasha Narwal, Devangana Kalita and Asif Iqbal Tanha remain in jail, with Delhi Police claiming procedural delays in verifying sureties and addresses, and filing a last-gasp petition to deny their release at this time. Ms Narwal, Ms Kalita and Mr Tanha had moved the trial court for their immediate release after they remained imprisoned past the 1 pm deadline set by the High Court yesterday.
