A speech-impaired student remained trapped in the washroom of her school for over 10 hours in Shahrasti upazila of Chandpur district.
Around 12.30pm, after the school hours, Sharmin went to the toilet. However, office assistant Shahanara Begum Shanu locked the loo from outside without checking if anyone was inside.
As the girl was speech-impaired, she failed to raise an alarm, police said.
Around 10pm that day, Al Amin, a resident of the area, heard the groaning sound of the girl. He immediately broke open the door of the school toilet with the help of local people and rescued the girl.
Amir Hossain, headmaster of the school, said, "He left the school around 4:30 pm but had not spotted anyone on the premises then.'
Shahrasti Upazila Nirbahi Officer (UNO), Shirin Akter, said, “A probe has been ordered to find out if there was any negligence on the part of the school authorities. Action will follow, after the probe report."
