THE death of a tot who was battered like a “punchbag” after a catalogue of errors brought calls for a public inquiry last night. The 17-month-old boy died with 50 horrific injuries despite police, medics and social workers knowing he was at risk. His evil mum, her sadistic boyfriend and their lodger were all convicted yesterday. The Old Bailey heard how his spine had been snapped, his skull was covered in bite marks and fingertips were missing when he was found dead in his cot last August. The tot, known as Baby P, was being monitored by Haringey Council, which was criticised over the death of Victoria Climbie, eight, in 2000. But the trio’s campaign of terror went unchecked. Three people have been disciplined following a probe into the scandal. The boy’s death prompted Children’s Minister Beverley Hughes to order a review into Britain’s child protection services. He died despite being seen 60 times by medics, police and care workers. The boy, of Tottenham, north London, had been on Haringey’s “at risk” register for nine months before his death. His mum, who cannot be named, admitted causing or allowing him to die. Her boyfriend, 32, who also cannot be named, and lodger Jason Owen, 36, of Bromley, Kent, were found guilty of the same offence, but were cleared of murder. They face up to 14 years in prison. Their bullying was so extreme the baby would cower with his forehead on the floor, fearing another beating. The mum, 27, who was described as a “slob”, was accused of hiding the abuse by covering her son’s bruises with chocolate. Jurors were shown computer-generated images of Baby P’s injuries. Dr Sabah Al-Zayyat, a paediatrician at Great Ormond Street Hospital, failed to notice he had a broken back and eight broken ribs 48 hours before he was found dead. Dr Al-Zayyat has not had her contract renewed but is appealing. Det Supt Caroline Bates had recommended he be taken into care, but was over-ruled by social services. Social worker Maria Ward, a second social worker and a lawyer have been warned by Haringey Council. Sharon Shoesmith, chairman of Haringey Local Safeguarding Children Board, said: “All the signs were that we were dealing with a mother who had poor parenting skills. We can’t stop people who are determined to kill children.” But Mor Dioum, director of the Victoria Climbie Foundation, called for a public inquiry, saying: “This is even worse than Climbie because all the signs were there.”
