After a US firm claimed a Chinese government-linked group of hackers targeted India's critical power grid system through malware, Maharashtra Home Minister Anil Deshmukh on Tuesday said Union Power Minister R K Singh spoke to him over the issue and stressed on the need to remain vigilant.

Interacting with media persons outside the Vidhan Bhavan here, Deshmukh said the US company's report on suspected cyber attack on India's power grid should not be seen from a political point of view as it concerns the entire country not just Mumbai or Maharashtra.
