Two teenagers who kidnapped a schoolgirl and subjected her to 17 hours of torture have been jailed.

Caylen Candy and Chyanne Powell forced their victim, who was 14 at the time and can not be named, to strip naked at knife point, masturbate and sit in a cold bath. They also poured salt down her throat while filming the whole episode on their phones, according to The Times.

The attackers had been on a 12-hour drinking binge prior to the torture episode, during which they performed other degrading acts, such as cutting chunks from their victim’s hair and holding her head under water for up to 10 seconds at a time on three occasions.

When the victim asked why they were torturing her, they replied "It is just a bit of fun," according to The Hertfordshire Mercury.

The offenders snatched the 14-year-old from the street as she walked to school. They took her to Powell's flat in Waltham Cross where they carried out the series of horrifying acts, whilst recording it on their mobile phones.

Candy said: "You will get killed if you snitch us," according to Prosecutor Michael Speak.

The Hertfordshire Mercury describes 21-year-old David Appiah arriving at the flat where he was shown pictures of the naked girl before later sending light hearted texts to Powell about the girl’s torture.

Judge Stephen Warner said of the incident: "What was she was subjected to was nothing short of torture - physically and psychologically - done for your amusement and gratification.

"She was treated as an object rather than as a person."

Candy, was sentenced to six years three months in a Young Offenders Institution after pleading guilty, whilst Powell, was sentenced to seven and a half years, with a three year extended licence.

The licence was issued after the judge decided she was a ‘dangerous offender’.
