Commissioner of Police John Pennefather-Evans and Inspector Louis Whant are released from Stanley Prison and returned to the Camp in the morning. They'd been arrested on July 11 and June 28 respectively on suspicion of being involved with either the secret radios or the ration truck message system.
The other arrestees are handed over from the Gendarmes to the Prisons Department and interogated by the public prosecutor (Kogi). For the next two months they'll be held in the ' B' Block of Stanley Prison awaiting trial.
