Police baton-charged customers of e-commerce platform E-orange when they took to the street and tried to block the busy road near Matshya Bhaban area on Thursday.
Protestors claimed at least 10 of them were injured during the attack.
Witnesses said several hundred E-orange customers started gathering in front of the Jatiya Press Club around 11:00 am to press home their 10-point demand including steps to ensure immediate extradition of suspended police inspector Sohel Rana from India and confiscation of his wealth.
Later, they started marching towards Matshya Bhaban where they came under attack from police.
Moudud Hawlader, officer-in-charge of Shahbagh Police Station, said they dispersed the crowd as they tried to block the road. The OC said none were detained from the spot. Protesters, however, claimed that two of them were picked up by law enforcers.
On August 17, customers filed a case against the owners and staff of E-orange for reportedly embezzling around Tk 1,100 crore and not delivering their products.
E-orange owner Sonia Mehjabin, her husband Masukur Rahman, and some others are now behind the bars.
