Police swung into action around 3:40 pm as they continued their blockade despite repeated requests by the authorities of Shaheed Ramiz Uddin School and College.
The police chased the students through Shewra Bus stand where the angry students vandalised 8-10 buses.
Earlier, Ummey Kulsum, a teacher of the college, urged the agitators to withdraw their blockade programme as two drivers and two helpers of three buses of 'Jabal-e-Noor Paribahan’ were arrested by members of the Rapid Action Battalion (Rab).
“The authorities concerned informed us that Jabal-e-Noor won’t operate any bus on Mirpur-Uttara road. Besides, a footbridge and a speed-breaker will be set up in front of the college,” she said.
“Student representatives, college Principal, a joint commissioner of Dhaka Metropolitan Police and representatives of Dhaka Cantonment held a joint meeting in this regard. And they assured us of bringing the offenders to justice,” Ummey Kulsum added.
Defying her repeated requests, witnesses said, the agitators chanted slogans to continue their protest programme, prompting the police to swing into action and dispersed them.
