The Bombay High Court on Tuesday ordered the immediate release of a Yemeni national detained by the Mumbai police earlier this month for overstaying his visa and sought to know how he could be kept in a lock-up.

The court questioned how the man, Mohammed Qassim Mohammed Al Shibah, a former airline employee, could be kept in the lock-up at the Byculla police station since May 16, and noted his current detention was due to administrative lapses.
