A textile goods container exported from Faisalabad to United Kingdom, containing approximately 234kg heroin was seized by authorities in Yorkshire on Tuesday, Express News reported.
The British police arrested two suspected dealers and took them to an undisclosed location where initial investigations led to the arrest of seven other suspects from different parts of Faisalabad.
Further investigations are underway.
Authorities were puzzled over how the smuggling was taking place.
Involvement of government officials is suspected by authorities who were baffled by the smuggling due to its immense quantity.
The container was sent from a small industrial estate, but the name of the firm is yet to be disclosed by authorities as they suspect that those involved will go into hiding.
