Frank Hartley
From Tardis Wiki, the free Doctor Who reference
Frank Hartley was the son of Mr Hartley and the brother of Yvonne Hartley. He wished to be called up to the work crews who were breaking through the city roof to the surface of Mondas but he wasn't. After he realised what had happened to his sister and those who were called up, he helped the Fifth Doctor and Nyssa destroy the Cybermen. (AUDIO: Spare Parts)
