A teenage girl was held captive by a jealous ex-boyfriend in his room, a court has heard.
The 18 year old tried to escape by jumping from a first floor window but it was slammed shut on her fingers, a jury at Ipswich Crown Court was told.
William Mackenzie, 20, of Park Lane, has denied offences of false imprisonment, assault and causing damage to property.
The court was told Mackenzie had bombarded Donna Seymour with up to 20 text messages a day after their two -year relationship came to an end about a month before the incident.
Prosecuting, Alison Ginn claimed that Mackenzie became enraged when he found what he believed was evidence that Miss Seymour had been exchanging text messages with other men.
Giving evidence, Miss Seymour said that she had agreed to go to Mackenzie’s room in a shared house in the early hours of August 26 after she finished work at the White Hart pub.
“He asked to use my phone and I wouldn’t let him so he got really aggressive,” the court heard. “He wanted to read the messages,” she said.
After leaving the house, they both later returned when Miss Seymour said the defendant smashed her phone, searched through her bag and ripped her leather jacked in half.
Dragging her on to his bed he told her: “Before you go I want something from you” and cut off one of her dreadlocks.
She claimed her ordeal came to end after around three hours when Mackenzie let her go and she fled in the tattered remains of her clothes until she found the driver of a parked lorry who allowed her to use his phone to call her mother.
The trial continues.
