Without hearing it, unable to confirm or deny.
There are usually so many in a typical Dr. Who episode.
Yes very true.
Fwiw. In 1979 a serial killer was on the loose. He murdered unfortunate women who thumbed rides with truck drivers. An individual sent an audio tape to the leading police officer, taunting him about the killings he(voice) had done. It was a strong "Geordie" accent. This being Newcastle on Tyne. Quite different that a Yorkshire accent.
The police were observing a Yorkshire man - Peter Sutcliffe, had strong feelings he was the killer. The whole investigation switched to the "Geordie". Meanwhile Sutcliffe murdered three more women. Sutcliffe finally caught by good honest police surveillance.
25 years later the police got a tape of one John Humble, a Newcastle man. Forensics identified him. He got eight years in the slammer. A bit of a long screed by me, but if the swines ever got tape recorded and identified elsewhere, the authorities could forensically identify them.
