Chief Minister Devendra Fadnavis put in some serious overtime last night as he travelled to five different parts of the city to check on the progress on vital plans for Mumbai's metro. Wearing a hard hat, Mr Fadnavis, 46, travelled by road between midnight and 3:30 in the morning from the heart of the financial capital to suburbs that will be linked by the metro. The after-hours inspection was planned to prevent inconveniencing commuters.
