According to an article Junan no 16-nichikan (受難の16日間) by the editor, published in issue 30/31, the police raided his office and confiscated all the materials related to the magazine. He was imprisoned and interrogated for 16 days. The police concluded that the past issues of the magazine had contained obscenity and that it was possibly illegal that the magazine sold homoerotic photos to the subscribers.^[3]
