Patli union parishad panel chairman Nazrul Islam confirmed the death of three people.
Police and locals said Harun Mia is caretaker of a house owned by UK expatriate Bulu Mia in Sulemanpur. Harun Mia lived with his family at that house. A tree broke and fell on the tin-roofed house in which they lived when a nor'wester hit the area around 5:00am, killing the three on the spot.
