Flames suddenly erupted from a newly installed tube well while water was being pumped out at a house in Daganbhuiyan upazila of Feni, creating panic among locals.
The incident took place on Saturday evening at Patowari Bari in Korbanpur village under Sundarpur union of the upazila.
According to locals and eyewitnesses, businessman Md Hasan installed a new 110-foot-deep tube well beside his house on Saturday for household use.

After the installation work was completed, workers attempted to pump out water from the tube well in the evening when flames suddenly burst out along with the water.
Witnesses said the fire continued for nearly two to two-and-a-half hours before going out.
Ujjal Barua, Feni Fire Service and Civil Defence team leader, said they rushed to the scene after receiving information but the fire had already subsided before their arrival.
He said the incident could have occurred due to the presence of underground gas and advised informing the relevant authorities for further examination.
Saleh Ahmad, Deputy Assistant Engineer of Bakhrabad Gas Distribution Company’s Feni office, said a small amount of underground gas trapped beneath the surface during the installation of the tube well might have caused the flames.
