Patel (Frontier in Space)

Patel was a newly-arrived prisoner at the Lunar Penal Colony. He had been transported there on the same shuttle as the Third Doctor. His crime was that of sabotaging a military base. On the Moon, he was reacquainted with Professor Dale, a leader of the Peace Party. In his university days, Patel had served on the Youth Committee of the Peace Party, which was under Dale's oversight. (DW: Frontier in Space)
