Nido was allegedly beaten by a group of 5-6 men in the Lajpat Nagar market on Wednesday evening. He was found dead in his bedroom on Thursday. His friends and family have alleged a hate crime. Amid outrage, the police have registered a murder case against "unknown persons" and have reportedly detained one man.
His family says he died as a result of internal injuries after he was beaten up by shopkeepers in Lajpat Nagar market. The police have said the incident doesn't seem to be a case of hate crime and has cautioned that the autopsy report which will explain the cause of his death has not been released yet by doctors.
Officials at the hospital where the autopsy was conducted say physical injuries have been found, but it cannot be concluded whether they caused Nido's death. The detailed report is expected on Monday.
The Aam Aadmi Party has blamed the Delhi Police for his death saying it has to "take the responsibility to stop such incidents." Chief Minister Arvind Kejriwal says a magistrate will investigate the case as well. Union Home Ministry has sought a detailed report from Delhi Police over the incident.
Nido, whose father is a Congress law-maker in the Arunachal Pradesh legislature, was studying in Jalandhar and had travelled to Delhi for a holiday. His friends say that on Wednesday, while at the market, he stopped at a confectionery shop for directions. They allege that the men gathered there made fun of his hair and Nido asked them to apologise.
A fight then erupted and Nido allegedly broke a glass at the shop. Then, a group of five men attacked him with sticks and iron rods, according to his friends.
Nido's family claims that the police arrived and negotiated a compromise which included making the student pay the shopkeeper for the broken window.
Nido Taniam returned then to the house of a relative where he had been staying in Delhi. The next morning, his family says, they found him dead.
