Uttar Pradesh CM Yogi Adityanath on Thursday visited a seven-year-old boy, who is in a hospital after being allegedly stabbed in a toilet at his Lucknow school.

Police have taken a class 6 girl into custody who purportedly attacked the victim as she wanted a holiday in the event of a schoolmate's death.

The crime is reminiscent of Gurugram's Ryan School case where a student was accused of killing a boy at a restroom as he wanted the institute to call off an exam.

Though the Lucknow incident took place on Tuesday morning, it came to light on Wednesday when the matter was highlighted by the media.

The principal of Brightland School, Rachit Manas, has also been arrested.

According to reports, the victim, Hritik Sharma, is a student of Brightland College.

"I was inspecting the first floor when I heard some banging the door of the bathroom. Upon opening I was shocked to find Hritik with multiple wounds on his body and a cloth was also stuffed in his mouth," Amit Singh, the discipline head of the school said.
