The girl’s mother appealed directly to the prime minister, saying: “Please help. If it was your daughter, your niece, your son, your nephew, your family member, would you be happy?

“Because we’re not happy and I don’t think any other member of the public will be happy too. So you’re in a position of power to help, so please help.”

Her mother’s partner, who was in court with her when the sentences were handed down, said he’d felt “physically sick”, when he heard the judge’s decision.

He said: “It seems to me like the victims are the ones suffering and the perpetrators are the ones that have seemingly got away scot-free.”

In the sentencing hearing, one of the 15-year-olds was given a three-year youth rehabilitation order (YRO) with 180 days of intensive supervision and surveillance for the rape of each of the two girls and two indecent images charges.

The other 15-year-old was given the same sentence for three charges of rape against each of the victims and four counts of taking indecent images.

The 14-year-old boy was given an 18-month YRO for charges of rape in the January 2025 attack by encouraging one of the other defendants.

A government spokesperson said: “We share the public’s shock at the details of this horrific case, and our thoughts are with the young victims during this distressing time.

“The Law Officers are urgently reviewing the case with the utmost care and attention.”
