Hospital doctor (Doctor Who and the Silurians)

The hospital doctor was a member of the staff at Wenley Hospital. He emerged from the building after Baker had collapsed and died from the Silurian virus. He was stopped by the Third Doctor and the Brigadier, who informed him Baker had died of an alien virus. The Brigadier ordered him back inside at gunpoint and placed the building under quarantine. He later reported the doctor had contracted the virus. (DW: Doctor Who and the Silurians)
