Allen (Colony in Space)

From Tardis Wiki, the free Doctor Who reference

Allen was an IMC security guard under Captain Dent during the expedition to Uxarieus in 2472. He kept guard over David Winton and Jo Grant. When Jo and Winton managed to escape, he recaptured Jo but Winton managed to escape.

While bringing Jo back to the IMC spacecraft, a group of primitives arrived. Allen managed to shoot one but not before they killed him. (TV: Colony in Space)
