Rapid Action Battalion (Rab-7) yesterday detained three transport workers over pushing a primary-school teacher off a moving bus and running the vehicle over him, leaving him critically injured, in port city's Station Road area last Saturday.

The arrestees were identified as Mohammad Hossen (25), Mohammad Liton (35) and a 13-year-old helper.

Liton is the driver and Hossen the conductor of a bus of Showrav Paribahan in the city.

Addressing a press briefing at Chandgaon camp yesterday, Rab-7 Commanding Officer Lt Col MA Yusuf said Hossen had locked into an altercation with the teacher, Rahmat Ullah, over fare. At one point, they harassed and manhandled Rahmat.

"Later, they pushed him off the running bus and ran the vehicle over him, leaving him critically injured," the official said.

Rahmat, who teaches at Habibullah Govt Primary School at Panchlaish, was undergoing treatment at a private hospital.
