A teenager sobbed as she recounted how she was sexually assaulted by her headteacher weeks before she was burnt to death by a gang of students.
Nusrat Jahan Rafi, 19, burst into tears and cried hysterically as she told police about the way Siraj-ud Daula had touched her inappropriately in her hometown of Feni, Bangladesh.
But a cold-hearted officer, who has since been suspended, said: "It's not a big deal.
"Stop crying, nothing happened that you have to cry."
The headmaster was then arrested and remains in custody - but the video was leaked online, sparking a huge backlash for Rafi and her family.

She was forced to stay home as male pupils organised a rally for the teacher, but tried to attend an Arabic exam on April 6 by bringing her brother as protection.
There, she was lured to the roof by classmates who claimed one of her friends was being beaten up - but instead was met with a group of four or five girls wearing burqas.
They held her down, tied her up with a scarf, poured kerosene over her and set her alight before running away.
Their plan was to pass it off as a suicide, but she managed to run downstairs and and use her brother's mobile phone to record a video to name some of her attackers.
"The teacher touched me, I will fight this crime until my last breath," she says.
Doctors found she had suffered burns to 80 per cent of her body and despite efforts to treat her, she died four days later.
Now, senior police superintendent, Mohammed Iqbal, who is leading the investigation, says around 15 people have been arrested.
He says some of the accused claim they were ordered to carry out the attack by their headteacher.
"The plan was to pass the incident off as a suicide," he added.
"But it fell through after Rafi managed to come downstairs while on fire because the scarf burnt and freed her hands and feet."

Protesters have been marching to ensure Rafi's attackers are bought to justice, waving photos of her.
Prime Minister Sheikh Hasina has promised Rafi's family that no culprits will be "spared from legal action".
Meenakshi Ganguly, South Asia director at Human Rights Watch, said: "The horrifying murder of a brave woman who sought justice shows how badly the Bangladesh government has failed victims of sexual assault
"Nusrat Jahan Rafi's death highlights the need for the Bangladesh government to take survivors of sexual assault seriously and ensure that they can safely seek a legal remedy and be protected from retaliation."
