Tom Girton
From Tardis Wiki, the free Doctor Who reference
Tom Girton was an inhabitant of Devil's End and a member of the Master's coven. He informed the Master that the Third Doctor had arrived at the Cloven Hoof.
He later stole a UNIT helicopter and tried to kill the Doctor by driving him into Azal's heat barrier. After several failed attempts to do so, Girton accidentally crashed into the barrier, killing himself. (TV: The Dæmons)
