The detainees were identified as Ehsan Korim, driver; Ali Abbas, supervisor; and Vuttu, helper.
Asif Mohiuddin, additional deputy commissioner of the Detective Branch of CMP, said they picked up the trio from city’s Chandgaon area around 9pm on Saturday.
In a Facebook post that has gone viral, the student alleged that she was sexually harassed by the staff of a Shohagh Paribahan bus plying the Chattogram-Cox’s Bazar Highway on Wednesday.
According to the post, she boarded the bus when returning home from her sister’s residence.
At one point, after the other passengers all disembarked, she was left as the lone passenger on the bus. That is when two of the staff tried to violate her taking advantage of the empty vehicle.
She said she somehow managed to get out of the bus and escape.
