A teenager found dead in a park was in fear of being "fitted up" in the days before her death, a court was told.
Mary-Ann was warned by her family over her friendship
Mary-Ann Leneghan, 16, told an aunt that "there would be trouble" because her 18-year-old friend had set up a man to be robbed, a crown court jury heard.
Mary-Ann and her friend, who cannot be named, were abducted by a gang in May 2005. Her body was found in Prospect Park, Reading, Berkshire.
Six men are on trial for assault, rape, abduction, murder and attempted murder.
The Reading Crown Court jury heard that Mary-Ann had been warned by her family for some time to stay away from the older girl.
It is said that the set-up, on Adrian Thomas, also known as "Redz", was the motive for the revenge attack on Mary-Ann and her friend.
The two girls were abducted and subjected to repeated sexual assaults in a hotel room before being driven to Prospect Park to be killed, the trial has heard.
While Mary-Ann died from stab wounds, her friend survived being shot in the head and left for dead.
In evidence on Wednesday, Mary-Ann's aunt, Jennifer Hazelton, said her niece had been repeatedly advised by her family not to associate with her older friend, who was believed to be hanging around with drug dealers.
Mrs Hazelton told the jury that in the weeks before her murder, Mary-Ann told her about her friend setting up Mr Thomas to be robbed at his flat in Oxford Road, Reading.
"Mary-Ann said that when this boy found out, there would be trouble because of it," Mrs Hazelton said.
In an interview with police, Mrs Hazelton also said Mary-Ann had told her she was "in fear of being fitted up because of what (her older friend) had done".
