Forrest trial: Crush "became sexual relationship" A TEENAGE girl has spoken how a crush she had on her teacher at an East Sussex school developed into a full-blown sexual relationship before they fled abroad. The girl, who cannot be named for legal reasons, told how she held hands with Jeremy Forrest as they sat on a flight during a school trip to Los Angeles. The pair then started exchanging tweets on Twitter which developed into them sending each other private messages on the social networking website. In a video police interview from October 3 last year played at Lewes Crown Court on Tuesday, the girl said they chatted about music and school. Rumours about the pair began to circulate, she said, resulting in the school where Forrest taught - Bishop Bell C of E in Eastbourne - making them block each other online. The girl said: "After the holding hands had happened, people were getting suspicious and people were making up stories about what was going on." The girl said in the interview: "I asked a friend to get his number and we began texting for all of April and all of March. The texts started off with a lot of kisses. When we first began texting, we were gradually getting more like into a relationship, and there were photos and stuff like that, and there were other text messages. But we didn't start a relationship until the end of May and we decided that it was what we wanted to do. Around this time, we began to meet up outside of school. There were a few times when I would go over to his house ... and after that things got even more serious. The girl, dressed in a black top and jeans, said suspicions were raised at school but a full investigation was not launched at that point. Things stayed like that until the summer holidays when we began a sexual relationship which has been up until now. In the summer holidays, we were meeting up and texting. The girl said an investigation was launched at the school after it emerged that pictures had been sent between them. And she told how she "panicked" after a visit by police and a child protection officer. That night, September 19, following the visit by officials, she said she packed a bag and was going to leave that night. I wanted to leave because I didn't want to face my mum when she found out.
