It has emerged that social workers missed vital warning signs that led to a baby suffering catastrophic brain damage after being attacked by his mother's partner.
A serious case review found that the father of 13 month-old Slater Sharkey raised concerns in the weeks before his son was attacked, but officials failed to act.
Richard Morgan was convicted of manslaughter after he experienced what he called a "momentary lack of control" in December 2010 and attacked Slater while his mother was out.
The baby suffered 25 bruises to his body and died as a result.
Durham's Safeguarding Children's Board has now apologised for the failures and say recommendations have been acted upon.
