A case has been filed over the fire in the Tampaco Foils factory at Gazipur’s Tongi, which has claimed 31 lives so far.

Police said the family of one of the dead victims has filed the case on Sunday night.

Tongi police OC Md Firoz Talukder said the case accuses the owner and seven other officials of the company as well some unidentified persons.

The fatal fire broke out early on Saturday at the packaging factory after a boiler exploded.

Owned by former BNP MP from Sylhet Syed Mokbul Hussain, the Tampaco Foils packaging factory was set up in 1977.

“The chairman (Hussain) has been absconding since the incident. Arrests are yet to be made,” said OC Talukder.

Hussain’s wife ‘Parvin’ has been also named in the case along with Managing Director Tanvir Ahmed, General Manager Shafikur Rahman, managers Monir Hossain, Samir Ahmed and ‘Hanif’, and Deputy Assistant Director Alamgir Hossain.

It is not clear what charges have been brought against them.

The cases filed over the 2012 Tazreen Fashions fire and the 2014 Rana Plaza collapse accused the owners of manslaughter due to negligence.

The Gazipur district administration has formed a five-member probe body to investigate the mishap.

The fire service and the government’s Factory Inspection Department have also launched separate investigations.

Industries Minister Amir Hossain Amu has said action will be taken against anyone found guilty.
