The video was shot in 2019 during a ragging session by seniors at a Sri Lankan university.
Some social media users are sharing the video, claiming Indian right-wing organization Rashtriya Swayamsevak Sangh's (RSS) followers tortured Muslim girls by throwing water at them. Some argued that the boys belonged to Akhil Bharatiya Vidyarthi Parishad, a student organization affiliated with the RSS. In contrast, others claimed that boys from Karnataka are misbehaving amid the ongoing hijab row in the state. However, all these claims are baseless.
The video wasn't shot in India but is from Eastern University, Sri Lanka, and was shot in 2019. The video shows a bunch of seniors ragging the juniors at the university campus.
In February 2019, the video was posted by The Lanka Sun-News on Facebook, stating that the visuals showed ragging from Eastern University in Sri Lanka.
Through a reverse image search on the video's screenshots, we found that the same video was published by Puthithu, a news website run by Sri Lankan Tamils living abroad, on February 24, 2019. The report claimed that it is a fun video filmed from the Eastern University campus in Sri Lanka.
Further, a video posted by the Career Guidance Unit of the Srilankan university on their official YouTube channel in 2017 showed the university campus, which corresponds with the landscape in the viral video. (video ref- from 0:39).
Therefore, we conclude that the video has no connection with the ongoing hijab row in Karnataka, nor is it related to the RSS group in India.
