Alan Travers told about it in a Trans World Radio publication.  He was ministering in a church which had been infiltrated by Communist agents who reported everything that was said and done.  He wrote, "One of the men in the church was pointed out to me as the government spy who would report to the police the next day everything that was said in church that morning.  I was not surprised that there was such an informer there, but what did surprise me was that during the morning prayer session this man stood up and prayed and the congregation joined in with him."
