Four 17-year-old boys have been detained in Tamil Nadu's Tiruvallur district for allegedly attacking a migrant worker, Suraj, with sickles. The incident occurred on a train and continued at an abandoned railway quarter after the victim objected to the youths placing a sickle on his neck for a social media reel. The assailants, reportedly intoxicated, filmed the assault and posted it online. The victim, from Maharashtra, sustained severe injuries and is receiving treatment. The youths face charges including attempted murder. The incident has drawn political condemnation and calls for improved law and order.
