The teenager was heading towards Ganesh Nagar with his father on Sunday, when two men on a two-wheeler called him "gay", the police said.
When he protested, they started arguing with him.
Locals pacified the two parties and the scooter-borne men left, they said.
However, they returned with more men and visited the shop of the teenager's father. The teenager, his brother and uncle were present at the shop.
A case has been registered and the police were looking for the accused.
