Kolkata: Four years after Tata Motors Ltd abandoned its small car factory in Singur partly out of concern for workers’ safety, another company was forced to beat a retreat from West Bengal on Wednesday because the state administration couldn’t protect its executives from being assaulted by retrenched workers and political activists. Haldia Bulk Terminals Pvt. Ltd (HBT), a joint venture between Indian and French port logistics companies, said on Wednesday it was forced to abruptly terminate operations at the Haldia dock complex in view of the deteriorating law and order situation.
