A FORMER teacher at Holmer Green Senior School has today pleaded guilty to committing sexual offences against a child he groomed online.

Luke Fisher dramatically changed his pleas to guilty when he appeared at Aylesbury Crown Court today, on what was due to be the first day of his trial.

The 28-year-old former history teacher admitted to one count of meeting a child following sexual grooming and three counts of sexual activity with a child under 16, having previously denied all the charges against him.

The court heard the offences were committed against one girl over a period of three months after Fisher sent her Facebook messages that became increasingly sexually explicit over time.

Jurors were told Fisher - formerly of Vipont Court, High Wycombe, but now of Pinkneys Drive, Maidenhead - then met the girl twice, kissing her on both occasions before sexually touching her during their second meeting.

He was bailed ahead of sentencing at the same court on May 7, with Judge Francis Sheridan telling the court: "His career as a teacher is over."

He was placed on an interim Sex Offenders' Register and told he would not be allowed unsupervised contact with under 16s ahead of sentencing.

Mary Loram, prosecuting, told the court: "He developed a communication with her, originally over Facebook. They would message each other; it became increasingly explicit over time.

"The defendant and the girl agreed to meet up for what can only have been a sexual purpose. It's pretty clear from the messages.

"He did meet up with her on two occasions at his flat. He kissed her - not as friends kiss each other, but as boyfriend and girlfriend would. On the second occasion he went further than he had done on the first."

Fisher was found not guilty of a further allegation of sexual activity with a child, against a second girl, on the direction of the judge after the prosecution offered no evidence.
