A woman has sued seven policemen, including an officer-in-charge, accusing them of framing her son and his friend last week in what she says was a fabricated yaba case.

Meherunnesa, a resident of the port city's Pahartali area, filed the case yesterday with the court of Additional Chittagong Metropolitan Magistrate Shahdat Hossain Bhuiyan against the policemen of Pahartali Police Station, said her lawyer Babul Das.

The accused are Officer-in-Charge Rafiqul Islam, sub-inspectors Abu Sayed and Uttam Dhar, assistant sub-inspectors Fazlul Bari and Jintu Barua, and constables Nazim Uddin and Mohiuddin.

The court ordered Police Bureau of Investigation to investigate the case and submit its report in 30-days, Babul told The Daily Star.

Quoting the case statement, he said a team of police led by SI Abu Sayed picked her son Mehedi Hasan Nayeem and his friend Tanjil Islam up minutes after they left her house on Wednesday night.

Another young man was picked up along with the duo, but he was released hours later.

The lawyer said his client's son and his friend had been watching an IPL match before they went outside and got picked up.

When Meherunnesa went to the police station and asked about her son, SI Abu Sayed allegedly demanded Tk 3 lakh for their release, Babul said.

As the woman refused to give money, the officer verbally abused her, he added.

Police produced Nayeem and Tanjil before a court the next day stating that they were arrested in possession of 52 yaba pills, Babul added.

Contacted, OC Rafiqul Islam said police found the yaba pills by frisking the two young men.

He added that Nayeem was arrested in 2017 in a case filed with Kotwali Police Station.
