K Mahid Uddin, an Additional Commissioner of Dhaka Metropolitan Police, revealed the findings of the investigation at a press conference after the end of a two-day remand of Murad on Thursday. He said police seized Murads laptop and mobile phone for forensic tests.

Murad used to crack dirty jokes while giving lessons to the girl and other students at his private coaching centre, according to the police officer.
The girl was a dancer at the school and Murad often told her that he sees her video before going to sleep, Mahid Uddin said. "Police have found initial evidence that the girl was sexually harassed in November last year," he said.

Investigations into such allegations are based on the circumstances and some other factors. Police are trying to do that."
