Summer Gregg
17-year-old Summer Gregg, from Doncaster, said she thought she was going to die after being hit with a piece of wood and a metal chain while made to act like a dog
She was tortured by three people she considered friends for over eight hours. The trio were sentenced to five years each at Sheffield Crown Court.
Summer Gregg, 17, even considered jumping from a 50ft to the ground below to end her agony at the hands of three abusers.
Summer believed the 19 and 20-year-old attackers were her friends before they locked her in the flat and began beating her with a metal chain and a piece of wood.
The teenager said the trio made her "act like a dog" before discussing killing her and disposing off her body.
Summer said: "I was so terrified, I kept thinking they're not going to let me live. I begged them to stop it all but they just didn't care."
All three pleaded guilty to false imprisonment and wounding.
