A report has criticised Haringey Council, the police and extradition services following the murder of a six-month-old baby by his father.

The young boy, referred to in the Local Safeguarding Children Board (LSCB) report only as Child R, died in January 2015 due to head injuries caused by his father, and was also found to have signs of previous fractures to his left arm.

The father was convicted of murder in December and is currently serving a life sentence, but it was revealed by the report that Child R’s mother is a convicted murderer and was subject to a European Arrest Warrant.

It says the mother, who also used to work as a nanny in Enfield, served nine years in prison for murder aged 17, and had fled illegally to the UK while on parole and pregnant with her first child.

The independent review criticises the extradition service, police and Serco for failing to pass on vital information about the warrant, and for failing to raise concerns about the mother to social workers, as well as the 101 service for not taking the case seriously enough when contacted by concerned midwives after Child R was born.

Haringey social workers were also criticised for failing to record vital details about the mother’s arrest, and for not calling the police and NHS together for a case review.

The review does also say the mother played no part in the murder of her child, and she was cleared during the father’s trial of any wrongdoing.

Sir Paul Ennals, chairman of Haringey LSCB, said: “The review identified some occasions where agencies could have initiated assessments of the family, examining risks and identifying support needs.

“It does not identify a causal link between these occasions and his death, which it concludes could not have been anticipated. But some significant leaning has been identified and acted upon.”

Joe Derrett, spokesman for Haringey Council, said: “The circumstances surrounding the death of Child R are tragic and, while the independent review concludes it could not have been anticipated, we fully accept that the council, police, courts, probation and health missed opportunities to assess the family and share information.

“The council has already implemented the report’s findings by further strengthening social work practice, particularly in the way we work with partner organisations.

“We should never forget responsibility for the death of Child R rests with the father, who was convicted of murder.”

A Metropolitan Police spokesperson said: "The death of any child is a tragedy and the Metropolitan Police Service has welcomed the chance to contribute to the multi-agency Serious Case Review.

"The Met has a responsibility to ensure that it is able to meet the needs of children and that all staff have the training, knowledge and skills to identify concerns that may impact on a child's well-being and safety. This will ensure that children and young people living in or visiting London are safe and able to enjoy and achieve in life.

"The recommendations made are being addressed."
