Although many projects in the state are in limbo, this is the first major pullout after Tata Motors's decision to move out of West Bengal in October 2008.
What may have precipitated into the move was Trinamool Congress chief and West Bengal Chief Minister Mamata Banerjee's 'dissatisfaction'.
Banerjee had claimed on Tuesday that 'nothing has happened' at Haldia, when asked about the abduction of three HBT officials.
She labelled it a conspiracy of a section of the media and the Communist Part of India (Marxist).
The company's counsel today informed the Calcutta High Court that the company would terminate its operations in Haldia.
ABG has also written to the Kolkata Port Trust, seeking termination of its 10-year contract with the port.
The move would put 350 jobs in jeopardy.
The company will also approach the court seeking compensation for the losses that it suffered at Haldia, including the amount it paid for security.
Tata Motors had also asked for compensation from the state government for its losses at Singur.
The immediate trigger was the abduction of three HBT officials -- Manpreet Jolly, Jagadish Behara and Bushan Patil, including his wife and one-year-old daughter -- at gunpoint last Sunday by an unidentified mob, allegedly backed by the TMC.
Although they were later released, the officials were told 'not to come back to Haldia'.
This happened even after the firm paid more than Rs 17 lakh (Rs 1.7 million) for the deployment of police personnel towards restoration of peace, based on a Calcutta High Court order.
