And it seems that the rules that protect Carr’s new identity are so strict that they will extend to her child.

The former girlfriend of Ian Huntley, who killed 10-year-olds Holly Wells and Jessica Chapman in 2002, was given a new identity after serving 21 months for covering up for the killer.

A rare court order giving lifelong anonymity means that even Carr’s child will never know its mother’s true identity. It also means that the child’s identity will in all likelihood be protected by a court order.

Carr is believed to have given birth at a secret address earlier this year.

It is thought that a new court injunction will have to be made to protect her baby’s identity.

Carr is one of four people to have been given secret identities in the UK. The others are Mary Bell, who murdered two young boys when she was just 11, and Jamie Bulger’s murderers Jon Venables and Robert Thompson.

Carr told police that she was with Huntley on the day of the killings in 2002.

Huntley, a school caretaker, was eventually sentenced to life imprisonment for the murders.

Although Carr was not herself implicated in the killings, in lying to police she delayed the investigation and was convicted of perverting the course of justice.
