The body of a 3-year-old boy was found inside a drain at a private school in Patna on Friday, after which his family, enraged, set the premises on fire.
The family also blocked roads, disrupting vehicular traffic movement and burnt tyres on the streets.
The boy's family had launched a search after he did not return home from school. They inquired about the child's whereabouts, but the school told them he had returned home.
The family persisted in their search, eventually leading them to the discovery of the boy's body. Deep within the school premises, concealed within a drainage gutter, they found the body of the three-year-old.
A senior police official said, "A case of child abduction was registered yesterday, after which an investigation was done and CCTV footage was checked. It was found that the child had gone inside the school but did not come out. During the investigation, two children of the school admitted that the boy's body was kept in the sewage of the schoolroom."
Police have so far taken three people into custody.
