Bhubaneswar: Security was tightened at National Aluminium Co. Ltd (Nalco) bauxite mine, after the company received a letter from suspected Maoists threatening to attack the site, an official said on Wednesday.
“The letter came to us by post few days ago and we have beefed up security,” said P.K. Mohapatra, executive director (mines and refinery).
In April, Maoist rebels attacked the mine in Orissa and killed 10 police before fleeing with explosives.
The mine which has a capacity to produce 4.8 million tonnes of bauxite a year for the company’s refinery nearby, had seen a temporary fall in output after the attack in April.
In the letter, the rebels asked Nalco to provide 2,000 contract labourers with permanent jobs within a month.
