Father Says 'I Want Them To Rot' The father of murdered Daniel Pelka has told Sky News his son was failed by both his school and British social services, who should have done more to protect him. Speaking from his home in northern Poland, Eryk Pelka, Daniel's biological father, said he hoped his former partner and her boyfriend would spend the rest of their lives in prison for starving and torturing Daniel, and that they should be made to suffer as he did. He said they alone were guilty of his murder but questioned why "nobody reacted in time" to ask why he was so hungry and raise the alarm. Daniel's father moved back to Poland when he was around one year old. Daniel was so hungry he stole food at school His relationship with Daniel's mother, Magdalena Luczak, had broken down and he said she was often drunk and violent towards him, at one point threatening him with a knife, but he believed she would take care of their son. Had he known the truth, he said he would have brought Daniel back to Poland immediately and raised him there. The last time he saw his son, he remembers him as a happy, healthy, energetic little boy, who was learning to walk and "really chubby." He said: "He was, how would you say in English, 'a lovely boy'. Sometimes he was a bit naughty, but every child is. We did not have any problems with him. He was chubby when he was small. Even I remember we were making fun about the British milk, that it is working like that. He was really chubby. He looked like a little tomato when he was crawling. Daniel's mother should be made to suffer like him, his father says He was doing everything, playing with everything. The flat was full of him. He said he had tried not to read the details of what happened to Daniel, but he knows his son was starved and beaten, and that he was seen eating food from the bin at school. "I can't imagine what Daniel felt through that time, what this child had to go through," he said. This child had about 50 bruises, even signs of teeth marks. Can you imagine? This was just a tiny boy. He travelled to Coventry to give evidence against Daniel's mother at the trial. He said he tried not to look at her, but at one point he caught sight of Luczak in the dock. I would just like to kill her. And that's it," he said. Or maybe better, I would like her to stay in prison with Mariusz till the end of their lives, so they can suffer like they made Daniel suffer. To make them feel the same as they did to him. His father remembers him as a chubby, healthy, happy boy I want them to rot. So they never see sunlight again. Eryk Pelka moved back to his native Poland in 2008. He has since married, and has a young daughter, Claudia, who would have been Daniel's half-sister, as well as his wife's daughter from a previous relationship. They are not rich. They live in the small, somewhat neglected, northern city of Grudziadz, where he works as a welder. The area has suffered with the closure of local factories, and unemployment here is around 21%, but the Pelkas' small flat is neat and decorated with flowers, and they are working hard to give their children the best possible start in life. "If Magda had called me and said that she couldn't cope with the child, I would take Daniel here to Poland for sure," he said. We have two kids right now, we would have three then, and Daniel would be alive. And nothing bad would happen. Mr Pelka attended gave evidence at the trial Mr Pelka was very clear that Luczak and Krezolek were to blame for Daniel's death, but he says the professionals, who saw Daniel losing weight and stealing food, could have done more to find out what was happening to him. "If people in school saw that he was taking a food from bins, they should do something." he said. They should send the police or social services to check the situation at home, check what were they doing with the child. That nobody reacted in time. I am sure social services could have done more, the same with the school.
