Hundreds of people have protested in Delhi against the beating and subsequent death of a university student from north-eastern India.
Officials say 19-year-old Nido Tania was beaten on Wednesday by shopkeepers who had ridiculed his appearance. He died the next day.
Two people have been taken into custody.
The case has highlighted racism and discrimination against indigenous minorities from India's north-east.
The Delhi police have been accused of being slow to respond to the assault on Mr Tania, who was reportedly on holiday in the Indian capital.
Protesters, many of them students, gathered outside a police station on Saturday near where Mr Tania was attacked in the south Delhi suburb of Lajpat Nagar.
He was the son of a member of the Arunachal Pradesh state assembly.
Indigenous people from India's north-east, who are ethnically closer to people in Burma and China, often say they encounter racism and discrimination in the rest of the country.
