New device which marks criminals with indelible dye.
Demonstration of a new device which marks criminals with indelible dye.
Various shots of a man walking out of a bank with a briefcase. He puts a "truncheon like instrument" ( a "cosh") into his pocket. A thief makes a grab for the briefcase and runs off down the street with it. Our man runs after him and launches a stream of indelible dye at the man's back. The dye launcher is called "the criminal detector". It is pretty cheesy, even for 1956.
Another man apprehends the robber and struggles with him. As he is pushed towards the camera we see splattered ink on the back of his Macintosh.
