A married schoolteacher allegedly had sex with a 15-year-old pupil in a field before sending him topless pictures on Snapchat, a court has heard.

Kandice Barber, who is now 35, is also claimed to have told the boy she could be pregnant with his baby after they had sex following an awards evening at a secondary school in Buckinghamshire.

Barber, who has school-aged children herself, has denied the charges.

She told detectives her Snapchat account must have been hacked after nude pictures were sent to the pupil and circulated throughout the school.

Barber’s headteacher is said to have found out about the alleged affair when he discovered the snaps being spread between pupils.

The court was told Barber added the 15-year-old school kid on Snapchat after a school sports awards day in September 2018.

The married school teacher allegedly had an affair with a student

She is then accused of picking the youngster up in her car and driving him to some fields where they had sex.

Jurors at Aylesbury Crown Court heard the teacher met up with the teenager for two more illicit encounters and sent him topless photos.

As the alleged incidents continued, Barber had texted the pupil to tell him he “looks fit”.

Her topless pictures were widely shared around the school, it was alleged.

By the start of last year, the headmaster at her school came into possession of one of the topless pictures, which were circulating along with rumours of an alleged illegal abusive sexual relationship.

Richard Milne, prosecuting, said: "This case is about an adult teacher having sexual relations with a pupil at the school where she taught.

“He (the victim) was not proud of what happened, he was not showing off, it was not some sort of fantasy. He was extremely concerned and nervous when the rumours were going around.

"He knows that they did not have sex after his 16th birthday because she had proposed a hotel as a special treat for his 16th birthday, which he politely declined."

In a video interview with police given on March 11 last year, the boy claimed the two had continued messaging for months after he turned 16, only stopping because the school staff found out.

The boy added that when called in to speak to his headmaster, he had initially denied that he had sex with Barber.

Speaking to a member of the child abuse team at Aylesbury police station, the boy, who cannot be named for legal reasons, said: "I lied because she had told me she could be pregnant with my child and I began to panic. I lied to pretty much everyone except my friends.

"She said that if I was going to snitch, snake on her basically, she was going to bring me down with her. I was like, are you going to accuse me of rape? She was like, dot dot dot. Obviously I got angry and I did not talk to her after that."

Other pupils at the school had started approaching the complainant after Barber became pregnant, the court heard, because it was thought he might be the dad.

The boy told police: "She was pregnant and she missed a lot of school. A few people came up to me and asked me the question. She said she did not know if it was mine or her husband's.

"If it was mine, I was too young to deal with that as a situation. Then she phoned me, saying that she had a miscarriage. She sounded upset, she had just been crying.

"I did not really understand what it was at the time, I did not know if it was my fault."

Barber was arrested on March 12 last year and during the interview she produced a prepared statement where she denied having sex with the boy, claimed her pregnancy was widely known around the school, although she later lost the baby, and the dad was her husband.

Mr Milne told the jury: "She denied having sexual intercourse with the boy but did admit sending the boy a picture of herself topless.

"She said that she was going through a bad patch with her husband, that she was pregnant but lost the child, they wanted another but it was not happening.

"Things were strained between her and her husband. The boy had paid her attention and she had let her guard down and started to talk to him."

The 35-year-old denied having sex with the teenager

A social worker attended Barber's home the following day and assessed her but during the visit Barber accepted having sent a topless picture to the boy, the jury heard.

The court heard how the social worker had visited Barber again and the defendant had asked that what she had said not be included in any official reporting, adding she would deny having said it.

Mr Milne added: “The defence is likely to be that she, the defendant, did not engage in any sexual relationship with the complainant. In other words, it is simply made up.

Barber, from Wendover, Buckinghamshire, denied three counts of causing or inciting a child aged under 16 years to engage in a sexual act, one count of sexual communication with a child, one count of causing or inciting a child to engage in sexual activities while in a position of trust and one count of causing a child to watch a sexual act by a person in a position of trust.

Explaining the position of trust charges, Mr Milne said: "In this jurisdiction, England and Wales, teachers are not permitted to have sexual relations with pupils and it is not to do with the age of consent, it is because they are in a position of trust, be they male or female.

"The law does not permit, indeed criminalises, any sexual activity between a teacher and a child under the age of 18 years, even if they were consensual relations."
