Security guard (Logopolis)

A security guard was a member of the security personnel at the Pharos Project.

Biography
The guard and two colleagues were on guard when the Fourth Doctor, and Tegan were trying to reach the radio telescope. The Master prepared to fire at them with his Tissue Compression Eliminator, but the Doctor snatched the weapon from him and threw it away. The noise attracted the security guard's attention and he led his colleagues in pursuing them.

After the guards lost sight of them, Nyssa and Adric approached, claiming to be answering the project's message, and Tegan also ran over to berate them. This distraction gave the Doctor and the Master the opportunity to reach the antenna control room. After the two Time Lords had repositioned the dish, the security guard raced to investigate, but arrived at the control room just after the Master's TARDIS dematerialised. (TV: ''Logopolis)
