Melissa Reid has told her father about the night she claims Colombian gangsters forced her at gunpoint to smuggle drugs from Peru.
She said: "I could feel the metal against my temple.
"I thought they were going to kill me. They said they knew all about me and my family. I was so scared they were going to hurt them if I didn’t do as I was told.
" I didn’t know they wanted me to take drugs or money or guns at that point."
Melissa says she first met fellow suspect Michaella McCollum Connolly, from Northern Ireland, in one of the gangsters’ dingy hideaways in Palma.
They were kept captive in a flat, she said, then flown to Lima separately.
Melissa Reid and Michaela McCollum appeared in court in Lima, but it is unclear whether they have been charged, their lawyer said.
Two women accused of smuggling 12kg of cocaine into Peru could face up to three years in custody and a maximum of 25 years in prison.
A British woman accused of drug trafficking in Peru said she and her friend "were not smuggling for money, we were smuggling for our lives."
