Tritta was arrested before being released on police bail, with strict conditions not to either contact the girl or visit her home.
But he ignored those orders and twice travelled 200 miles (322km) from Hampshire to the victim’s house, broke the doorbell camera at her house and let himself inside.
He also sent her two cards, asking her not to support the prosecution as well as reporting her family to social services. He falsely claimed her mother had drugs in the home.
During his police interview, Tritta was asked if he knew whether his actions had been illegal due to the girl’s age.
He replied that he now knew because he was under investigation.
In a statement read out in court, the victim’s mother said her daughter was just a child when she was targeted and manipulated by Tritta.
“She now lives with fear and anxiety and goes to therapy because of the stress,” she said.
Karina Lyon, from the Crown Prosecution Service, said Tritta had preyed on the young teenager.
“His actions, for his own sexual gratification, have caused fear and anxiety for the young victim and her family,” she said.
“Not only is Tritta a sexual predator, but he has also exhibited deeply troubling behaviour by attending the girl’s address in breach of his bail and a court order, damaging property and trying to interfere with witnesses.”
