"If Duncan cannot run its tea estates, they can quit. We will run the tea estates," Banerjee told a public meeting here.
The Chief Minister said she had ordered resumption of drinking water and electricity supply to the tea gardens owned by the Duncans Group.
The Criminal Investigation Department (CID) of West Bengal government launched a probe earlier this week into the closure of 13 tea estates of the G P Goenka group in the wake of worker deaths.
Tea workers have alleged that 11 tea workers of the G P Goenka-owned Bagrakote tea estate had died of malnutrition in the past one month as the company had not paid its workers for the past few months.
Goenka had, however, said only one person had died at Bagrakote tea estate and that the rest of the allegations were "baseless canards".
A complaint was filed with the Darjeeling district police last month, alleging cheating and criminal misappropriation of properties by the firm. The case was transferred to CID.
"We have registered a case against G P Goenka and his son under Sections 406 (criminal breach of trust) and 420 (cheating) of the Indian Penal Code," he added.
Duncan Industries wholetime director M H Chinoy submitted documents related to the issue during his four-hour-long meeting with CID officers at Bhavani Bhavan yesterday.
The state's health department has set up a medical camp at the estate.
