As part of his plan to escape the prison, Evans expressed his desire to learn German and passing O-level examination. The prison authority after consulting the board, allowed a tutor to come into the cell and give him tuitions in German. In fact, the tutor was part of his team arranging his escape. Evans was to appear for examinations. The test would be given in the prison cell and a priest was arranged as an invigilator. At the end of the test, Evans impersonated as the invigilator McLeery and remained inside the cell, pretending to be injured while the other escaped. In fact, it was the invigilator who had come wearing two coats, two collars, two pairs of spectacles and two false beard and the pig blood in a rubber tube. As a result, in spite of strict vigil by the prison authorities, he was able to escape from the prison.
