As outrage mounted over the killing of a Tripura student in Dehradun in an alleged racist attack, Uttarakhand Chief Minister Pushkar Singh Dhami on Sunday said such incidents were unacceptable and the government would deal strictly with the culprits.

Five out of six accused persons have already been arrested, while the mastermind is absconding, the police said. Police have announced a reward of Rs 25,000 for the only absconding accused, a resident of Nepal, and said they have sent a team to the neighbouring country, while five others, including two juveniles, have been apprehended.
