A school worker allegedly begged a pupil aged 15 to hide her identity and delete Instagram messages after grooming him, a court has heard.

Melanie Rock, 34, said to the schoolboy she was 'f***ed' if he answered any questions about her so asked him to lie that he was at a skate park, jurors were told.

This was after she had allegedly been seen by another teacher taking the boy to lunch at a fast food restaurant, before taking him to her home.

It is alleged that Rock had lied about the young man being her godson to the teacher and had asked him to repeat the lie.

The communication support assistant at Medina College on the Isle of Wight has pleaded not guilty to meeting a child following sexual grooming and sexual activity with a child by a person in a position of trust.

Isle of Wight Crown Court has been told this week that Rock groomed the pupil at Medina College by taking him out for meals and buying him expensive clothing.

Jurors were told she brought him back to her home to show off sex toys and 'koala hugged' him on her bed by wrapping her arms and legs around him.

Rock had been seen by another teacher eating with the pupil, it was heard.

After she learned the school had contacted the boy about it the next day, she allegedly messaged him about fears she could lose her job.

The boy had told Rock the school knew about him 'going to McDonald's with a teacher', which was later corrected to Pizza Hut, and the two began exchanging messages about the discovery.

In one message, read to the jury, Rock wrote: 'WTF, and we didn't go to McDonald's, but f***, I'm f***ed, I'm going to be sacked now they found out.

'They are going to ask you questions: who was it, how do you know her, etc etc. If they know it was me, I'm f***ed.'

One message read, 'I beg you, don't say my name, please keep saying you were at the skatepark,' while another stated: 'Please I beg, do not mention me, because I would be done, trust.'

The court heard the boy blocked Rock but did not delete their messages which were later recovered by police.

Prosecutor Tim Devlin challenged Rock over the messages during cross-examination.

He asked: 'What is that message about if it's not a cry for help, "Don't tell them it was me",' to which she replied: 'I don't know.'

Earlier, Eleanor Fargin, defending, had asked Rock why she had told the boy to delete their messages, to which she also said: 'I don't know.'

Rock acknowledged she must have sent the messages but said she could not remember sending them or why.

She told the court she could not remember how her contact with the boy on Instagram began or whether she had been the first to message him.

She repeatedly told Mr Devlin she could not remember meeting the teenager outside school, collecting him in her car or arranging to see him during the October half-term.

She did accept that CCTV showed her with the boy at KFC.

Asked why she bought him food, Rock said: 'If a kid tells me, "I'm hungry", I'm not going to let them starve.'

She denied giving the teenager money, apart from possibly £1 for an amusement arcade, and denied buying him vapes.

The court heard evidence that the boy's phone had attempted to connect to Rock's home wifi.

Rock said she could not remember meeting him and denied inviting him into her home that day.

She accepted that CCTV showed her at Pizza Hut with the boy.

She said she could not remember the visit but later described a 'medical episode' at the restaurant that day.

Rock also denied telling a Medina College teacher, Joe Murdoch, that the teenager was her godson when they encountered each other at Pizza Hut.

Mr Murdoch previously told the jury Rock said the boy was her godson, that she had told no one and did not want colleagues to think the situation was 'weird'.

Rock maintained she had not said this and could not remember speaking to Mr Murdoch at his table.

The jury also heard further evidence concerning allegations that Rock had shown the teenager sex toys and lingerie in a drawer at her home.

Rock accepted that the bottom drawer in her bedroom contained nine sex toys, bondage shackles and lingerie.

However, she denied telling the boy to look inside the drawer or showing him any of the items.

She also denied telling him to 'enjoy my room' or inviting him into her bedroom to vape or call his mother.

Asked whether she had 'koala hugged' the boy, Rock replied: 'No, hell no. Why would I hug a child apart from my own child?'

She responded, 'No,' when Ms Fargin asked: 'Did you have a sexual interest in the child?'

Asked why she met the boy outside school, Rock said: 'I was doing my job. I'm a mum, I care, I care too much. I was trying to keep an eye on him.'

She accepted that nobody at the school had instructed her to meet the teenager outside school.

Mr Devlin alleged Rock bought the boy two Trapstar tracksuits costing £355, the court heard. Rock said the tracksuits were presents for her cousin.

The prosecution questioned why the tracksuits were medium, the teenager's size, when Rock's cousin was only 5ft 2in tall, and the defendant said her cousin preferred wearing baggy tracksuits.

Asked by Mr Devlin how the boy knew about the tracksuits, Rock replied: 'I don't know.'

Rock also denied showing the teenager a photo of them on his phone or telling him she was buying the clothing for him.

During a police interview, Rock read a prepared statement denying she met the boy intending to have sex.

She accepted her behaviour had breached school policy but denied any criminal wrongdoing, the court heard.

Rock maintained she had not behaved sexually towards the boy and denied the allegations concerning physical contact in her bedroom while also denying having a sexual motive.

Ms Fargin asked Rock to clarify issues concerning her memory. Rock said her memory had been poor for a long time.

The court has heard that she has been medically diagnosed with both short and long-term memory difficulties and jurors have requested to see her medical records.

The trial continues.
