Shears
From Tardis Wiki, the free Doctor Who reference
Lieutenant Shears was an officer in the British Army. He found Lodge, the Third Doctor and Sarah Jane Smith guilty of looting and sentenced them to be held in a military detention centre until they could be tried by the civil courts. He didn't believe the Doctor when he claimed to be with UNIT. (TV: Invasion of the Dinosaurs (TV story))
