An art teacher has been jailed for four years after admitting having sex with a teenage pupil.
Blott admitted four charges of sexual activity with a child under 18
Ian Blott, 54, of Church Lane, Thwing in East Yorkshire, had an "intense" two-and-a-half year relationship with the girl.
Blott, formerly a teacher at Headlands School in Bridlington, was jailed at Hull Crown Court on Friday.
He earlier admitted four charges of sexual activity with a child under 18 and abusing a position of trust.
Judge John Dowse told Blott he had destroyed part of the girl's life, taking her innocence and leaving her suffering from post-traumatic stress disorder and bulimia.
He told Blott: "No words of mine can restore to her the innocence which she had and you took.
"You must know that you've destroyed at least part of this girl's life."
Judge Dowse said he was pleased to hear the girl, who is no longer a pupil at the school, was making good progress from the array of psychiatric problems she had suffered in the aftermath of her involvement with Blott.
He said: "She thought you loved her and you told her as much.
"She feels betrayed."
Speaking after the hearing, Det Insp Nigel Sawyer of Humberside Police praised the courage of the girl in speaking out about the relationship.
He said: "This young victim has displayed tremendous courage.
"She has had to endure the normal pressures that young people have in trying to study and be successful in her life but this has been set against a backdrop of abuse and victimisation.
"It is every parents' worst nightmare. We all warn our children about strangers but you automatically place your trust in teachers.
"Whilst Ian Blott should have been protecting, supporting and helping this young girl to develop academically, he chose to abuse his position and betray his profession and use his role to prey on a vulnerable child."
