The three, who have been identified as Santosh, Raju, and Srikanth in the age group of around 30 years, allegedly harassed the 18-year-old girl, who resides in their neighbourhood, last evening, a police officer said.
"The girl informed the matter to her brother and when he questioned them about the incident, the trio allegedly assaulted the youth and pelted stones on the girl's residence," Hayathnagar police station inspector Srinivas Reddy said.
Later, the girl's parents lodged a complaint with the police, who registered a case on charges of eve-teasing under relevant sections of the Indian Penal Code and launched a hunt to nab the three, who are at large.
