Citing the seriousness of the alleged 'cyber sabotage' which caused the massive power outage in Mumbai last year, BJP leader Sudhir Mungantiwar on Wednesday said that he will be writing a letter to Prime Minister Narendera Modi, urging him to handover the probe into the matter to the Central Bureau of Investigation (CBI).

"I will write a letter to the Prime Minister to hand over the 'cyber attack' investigation to the Central Bureau of Investigation (CBI)," Mungantiwar said during his speech in the Maharashtra Vidhan Sabha.
