The possibility of foul play or sabotage can’t be denied regarding the massive power outage on Monday in Mumbai, Thane and Navi Mumbai, Maharashtra Energy Minister Nitin Raut said in a tweet on Tuesday.

A grid failure had resulted in a massive power outage on Monday, PTI reported. It stopped trains on tracks, hampered those working from home and served a blow to the economic activity. 

It took two hours for the power supply to resume for essential services on Monday, following which other pockets started getting power in a phase-wise manner.

Chief Minister Uddhav Thackeray on Monday ordered an enquiry into the incident, which happened when one of the lines was undergoing planned maintenance.

After ordering a probe, the CM held a meeting at his official residence in afternoon which was attended by state chief Secretary Sanjay Kumar and representatives of power supplying companies like BEST, Tata and Adani.
