A 13-year-old girl was allegedly raped in the toilets by a boy who had been moved from another school for sexually assaulting two other students.

The boy had been convicted of two rapes just days after allegedly attacking the girl in the restroom of a secondary school in spring last year, her father said in a report by The Times.

The Crown Prosecution Service are deciding whether to prosecute the boy for this attack.

The girl's father has also expressed his anger at how the school handled the situation and for allowing the boy to be in school without supervision despite his convictions.

'What we've been put through is horrendous and truly scandalous,' he told the publication.

The father, who described his daughter as naïve, added: 'We've been kept at arm's length. The school won't apologise, we've been through the complaints procedure. It's a farce.'

The boy was immediately removed from the school after the alleged rape was made known.

A spokeswoman for the school in a statement: 'We are currently working with the police as part of their investigation.'

The girl’s parents also approached Ofsted, who first told the couple they could not help because they inspect schools rather than look into complaints.

The government education watchdog has since apologised in a letter to the family for their insensitivity.

In the letter, Ofsted said that they downgraded the school's safeguarding adding that it was not effective and deemed as inadequate.
