Bois Locker Room Case: The chatroom, exposed on Sunday by a girl targeted in the grisly group chats, has drawn massive anger, shock and disgust on social media.A 15-year-old boy from a reputable school was arrested on Tuesday.

Several Delhi schoolchildren were questioned by police during investigations into the “Bois Locker Room”, an Instagram group on which obscene messages and morphed photos of underage girls were shared.

A 15-year-old boy from a reputable school, who was a group administrator, was arrested on Tuesday.

Twenty other students from a few schools in southern Delhi identified by the teenager were interviewed yesterday and their phones were seized. The interrogation will continue today, police said.

Some members of the group were 18 and over, the police learned during the interrogation. These have also been identified, according to sources.

Sources say the students mainly claimed that they didn’t know much about the group and that they were added to it by others.

Police have yet to receive a response to his request for details on Facebook-owned Instagram.

The chat room, unveiled on Sunday by a girl targeted in gruesome group discussions, sparked massive anger, shock and disgust on social media. Students in grades 11 and 12 casually chatted with girls about “gang rape,” sexualized them, and greeted them in screenshots of cats that went viral on Twitter and other social media forums.

Some of the participants are thought to be as young as 13, which has sparked a debate about toxic masculinity and the objectification of girls who start school and the need to better control children’s internet activity.

In a statement, Instagram said it made it a top priority for its users to be able to express themselves “in a safe and respectful manner”.

“We absolutely do not allow behaviors that encourage sexual exploitation or exploit anyone, especially women and young people, and we have implemented content that violates our community standards as we have been informed,” a said a Facebook spokesperson.

The company said that objectionable content that violated its community standards was removed as soon as it was informed.
