An “academically weak” teenager in India killed a seven-year-old schoolmate because he wanted to get exams and parent-teacher conferences postponed, police said.

Indian police arrested the 16-year-old Wednesday for slitting his young schoolmate’s throat in September, AFP reported.

“He admitted during questioning that he wanted to shut the school to defer the exams and [parent-teacher] meeting,” said Central Bureau of Investigation spokesman R.K Gaur.

Investigators had initially detained a bus conductor they thought killed the young boy for resisting a sex attack.

But a spokesperson for federal investigators said they now have credible evidence against the teen, who could not be named for legal reasons.

He’ll be sent to a juvenile detention center until his murder trial.

Parents raised concerns about safety in schools after the young boy was found murdered in a school bathroom on Sept. 7, while experts worried about the academic pressures placed on students.

Nearly 9,000 students in India committed suicide in 2015. Health experts say many young people find it difficult to cope with the pressure to succeed and struggle to accept failure in examinations.
