Reading the file, they found out that Harry had been treated rather badly, but they didn’t care, because Harry would have loved them even more, when the time came to "save’ him from a bad home and make a perfect family reunion, which would rise their reputation. And in case, if someone accused them of child abandonement and endangerment or child abuse, they would make sure to tell everyone that they wanted to keep Harry safe from death eaters and explain them that sending him in the muggle world was the only solution to protect him and that they were unaware of how he was treated. But everything was destroyed by the replacement bond. Both Potters were through the case trying to find out, how Harry was taken from Petunia and Vernon. Then the case was about that Petunia hit the boy with a frying pan repeatedly on the head until he was unconscious. But she was stopped by a Japanese couple, who had called the police, and when they arrived Petunia was questioned with the couple. Since the couple made their statements about how Petunia had beaten the boy with a frying pan repeatedly and Petunia tried to deny the crime with the frying pan in her hand, it resulted to Petunia's arrest. James never thought that someone could be so stupid to have the crime weapon in your hand and still argue that you are innocent. The police searched the house and found a bloodied belt. They investigated the house and found Harry’s room, a cupboard under the stairs. So, to sum it up the Dursley family was involved with the abuse including their nephew Dudley. The police put an arrest warrant against Vernon Dursley and informed the muggle child services to remove Harry and their nephew, Dudley Dursley, from their custody. Vernon was arrested at work and Dudley was sent to the child services. When they found out about Dudley’s criminal behaviour and the child services could see that the boy was involved in the abuse, they sent Dudley to a correctional facility for youths, whereas Harry was sent to a hospital.
