Leaders of petrol pump and CNG filling station owners’ associations on Saturday gave a 48-hour ultimatum for arresting those involved in Thursday’s attack on a CNG filling station in the Sylhet city and looting its cash.
Otherwise, all the petrol pumps and compressed natural gas filling stations across the division would be kept closed for an indefinite period from Tuesday next, they threatened.
Leaders of the association made the demand during a press conference at the Sylhet District Press Club in the city in the afternoon.
A group of activists of Chhatra League, ruling Awami League-backed student organisation, led by the district unit vice-president Selim Chowdhury, allegedly launched an attack Thursday night at Surma Auto Care and Filling Station at Shibganj in the city.
They vandalised the institution, wounded the employees and looted Tk 7,00,000 from the cashbox after failing to realise money they had been demanding from the institution manager as extortion. 
Surma CNG Filling Station managing director Abdul Hasib Chowdhury filed a case with the Shah Paran police station Friday, accusing some 15 Chhatra League activists, including Selim Chowdhury, in connection with the incident.
The association leaders in the press conference alleged that the police arrested none and the accused were roaming free in the area.
The accused in the case even are giving threat to kill the Surma CNG Filling Station authorities as well as the association leaders if the case was not withdrawn, they claimed.
Bangladesh CNG Filling Station and Conversion Workshop Owners’ Association secretary Amiruzzaman Chowdhury read out a paper in the press conference.
He said Thursday’s incident was not an isolated incident, rather a part of the ongoing incidents of extortion, looting cash money of the petrol pumps and gas filling stations and giving death threat.
Bangladesh CNG Filling Station and Conversion Workshop Owners’ Association president Zubayer Ahmed Chowdhury, Bangladesh Petrol Pump Owners, Dealers and Distributors Association divisional unit president
Mostafa Kamal and Divisional Tank Lorry Malik-Shramik Oikya Parishad president Abdullah Al Mamun also addressed the programme.
They also urged for security of owners and employees of the petrol pumps and CNG filling stations and their assets.
