District No. 13 had an interesting case handled by Lieutenant McR—— and Operative L——. They searched the room occupied by the suspect and found two handbags and several suit-cases filled with clothing and some chemicals. They interviewed the subject. His registration card gave his serial and order number, and draft board status which was Class No. 5 Austrian. The operatives went back to report this to the Inspector, and upon returning found that the subject, his wife and sister had fled. By calling upon the different taxicab companies in the neighborhood, it was found that they had used a yellow taxicab to move their effects to an apartment several miles distant. A raid was immediately organized. Four men and two detective sergeants went to the new address, and the apartment was surrounded. One of the men saw a figure which appeared to be a woman, attempting to cross the area between the two buildings from one third story window to another, and he called to her to stop. One of the men inside the building, hearing the call, put his head out and found the subject on the window sill of the adjoining building in a very embarrassing position. It was not a woman, but the suspect, in woman’s clothes! He was hauled in and put under arrest. In the meantime an analysis of the chemicals had been made and they were found to consist of materials for the manufacture of enough explosives to blow out another end of the postoffice building. Information was received from the League at New York to the effect that he was a very dangerous enemy alien.
