The arrestee was identified as Shamim Mia, son of Abdur Rab Mia. He is a driver of Swadesh Paribahan bus service.
Locals said the victim was going to Sonargaon’s Charkishoreganj from her Gazaria office. Other passengers got down at Morgapara Chourasta.
The driver took the girl to Asariarchar area instead of Meghnaghat. He handed over the steering to his assistant around 10:30pm and pounced on the girl.
Around that time, a local trader, waiting for bus in the market area signalled the vehicle to stop. But the bus tried to speed away from him.
The trader heard the scream of a woman coming from the bus. He started shouting and chasing the bus. People present in the market promptly blocked the road, forcing the bus to stop.
Locals caught the driver and beat him up before handing him over to police. The driver’s assistant fled.
Sub-Inspector Tawhid Ullah of Sonargaon Police Station said they arrested the driver and seized the bus.
The victim has filed a case in this regard.
