The police said the tailor had been threatened several times by some groups.Police said they had arrested the men for the incident, suspended internet services and appealed to people not to share the video. A curfew was imposed in some areas of Udaipur district and gatherings have been restricted.Ashok Gehlot, the Chief Minister of Rajasthan appealed to people to stay calm and not share the video as it would “serve the attackers’ motive of creating discord in society”.The police have also warned against sharing or circulating the video, calling it “too grisly” to watch.
