A mother locks her two young daughters inside an alarmed room every night to protect them from her paedophile husband – with the blessing of social workers, police and probation officers.
The 'safety plan' has been approved in Devon. Officials are said to be reassured that the woman's husband, once jailed for attacking a child under 13, would have to climb over her in bed and wake her up to get to the girls.
Officials are also reported to be happy that the children could contact their mother using a baby monitor if they needed to get out in the middle of the night.
The children's grandmother has criticised the plan.
She told the Sunday Mirror: "The alarm and the other so-called precautions to stop my granddaughters being abused are a load of rubbish.
"Since learning my daughter's new husband was a paedophile I've tried to express my concerns to social services. I'm appalled this man was allowed to move into the family home with my granddaughters. Other family members also feel their concerns are being ignored.
"It feels like my granddaughters are isolated and at risk. Social services don't seem to want to listen to me. It's heartbreaking, but I have to keep fighting this for the sake of the girls."
The man has to sign the sex offenders' register and is subject to a Sexual Offences Prevention Order, banning him from unsupervised contact with under-16s.
However, the Devon Multi-Agency Safeguarding Hub - made up of police, probation officers and social workers - gave the green light to an application by the mother to become an 'approved person'.
This allowed her to supervise contact between the convicted paedophile and her children.
The council said professionals were convinced 'there are enough protective factors in place for the children'.
A spokesman added: "Numerous reviews by a variety of agencies have concluded that his partner, who wants him to be able to stay overnight, can adequately supervise him.
"A safety plan has to be in place and his partner has to supervise contact at all times. The police have been informed and the local authority is monitoring the situation very closely with regular visits to the family home."
