Guard (The Crimes of Thomas Brewster)
From Tardis Wiki, the free Doctor Who reference
A guard at Baker Street Station was on duty when Evelyn Smythe arrived, having fled from Thomas Brewster. She attempted to enter the Baker Street tube station without paying, only for the Guard to stop her and tell her that she needed to use an Oyster card. When she told him she didn’t have one, he told her to buy a Ticket. Evelyn then forced him to hold her handbag while she payed for a ticket. (AUDIO: The Crimes of Thomas Brewster)
