The Raigad district disaster management cell had taken into account the sunstroke possibility at the Navi Mumbai event on Sunday and made arrangements but as water in tankers and taps became hot due to heat, many attendees couldn't quench their thirst and suffered dehydration, officials said on Monday.

At least 13 people died of sunstroke after attending the program held in an open ground in Kharghar area in Raigad district where social worker Appasaheb Dharmadhikari was conferred with the Maharashtra Bhushan award by Union Home Minister Amit Shah.
