Police have detained two students of the Indian Institute of Technology, Guwahati (IITG), for allegedly molesting three students of Gauhati University, police said on Wednesday.

The alleged molestation took place on February 3 but came to light only on Tuesday after the girls registered an FIR alleging molestation.

The victims said the incident took place when the educational institution was celebrating its annual festival "Alcheringa".

"The programme was over by 10.30 p.m and we were looking for accommodation in IITG on rent. At this stage the accused promised to help us," said one of the girl students.

They were later offered some soft drink. After consuming it, they felt dizzy, the victims stated.

"I could sense someone was trying to molest me. I tried to resist but lost consciousness. However, one of my friends remained conscious and she witnessed the molestation," the girl said in the FIR.

A police official said the two youths had been detained.
