Several firefighting units have been dispatched to the factory in the Bayezid Textile area
The duo - Sabbir Hossain and Ashiqur Rahman - surrendered to the court of Dhaka Metropolitan Magistrate Sarfuzzaman Ansari on Feb 9. The court had sent them to jail.
On Monday, Metropolitan Magistrate Nurunnahar Yasmin granted them bail in the case filed over the Oct 27 incident.
Dhaka Bar Council President Saidur Rahman Manik stood for them in the hearing of the bail petition.
He argued that the two acted in line with the law by surrendering to the court even though they had been granted bail earlier.
