Teachers, care workers and police are all criticised in the review, which revealed concerns over the failure to protect young children from abusive adults.
Despite the police receiving 26 reports of domestic abuse in the Pelka household, the serious case review found the Polish youngster, was "invisible" at times and "no professional tried sufficiently hard enough" to talk to him.
The court heard how the school child arrived at school with bruises and facial injuries, and was often so hungry that he scavenged in the bins for food.
He was also treated in hospital for a broken arm, and described by a teaching assistant as a ‘bag of bones’ weighing just 1.5 stone- facts which were described as ‘unknown’ by the professionals involved.
According to the report, Daniel suffered months of abuse, before being beaten, fatally wounded and left in an unheated box room for 33 hours to die.
The case review found that officials “demonstrated a failure of the most basic aspect of child protection work”.
Other contributing factors were said to be the level of deception from his mother Magdelena Luczak, 27, and her partner, Mariusz Krezolek, 34, who were jailed for life earlier this year for murder.
Noone has been disciplined as a result of the Pelka case review, with head of the review Ron Lock concluding that the professionals involved were ‘too optimistic’ about what they saw.
Explaining why no individual agency was blamed, Lock said:
‘It could be argued that had a much more inquiring mind been employed by professionals about Daniel’s care, and they were more focused and determined in their intentions to address those concerns, this would have offered greater protection for Daniel’.
‘Workload was a potential issue - child protection is a very complex matter - and perhaps when they felt reassured they moved on to the next case.’
‘But they need to be stronger and have a much more inquiring mind. They needed to act on what was in front of them.’
Martin Reeves, chief executive of Coventry City Council, said:
‘Daniel was murdered by the two people who should have loved and protected him most, but all organisations in Coventry involved in Daniel’s short life now have to face up to their responsibilities and the part they played in the missed opportunities that could have protected Daniel. We are sorry we did not do enough to protect Daniel.’
