Security guard (The Curse of Clyde Langer)
From Tardis Wiki, the free Doctor Who reference
The security guard worked in the anthropology department at the Museum of Culture in Ealing in 2011.
After Clyde Langer was affected by Hetocumtek's curse and was sent away by his friends he went to the museum. There Dr Samantha Madigan said Clyde's name and everyone, including the security guard turned against Clyde. The security guard threw Clyde out of the museum. (TV: The Curse of Clyde Langer)
