Bangladesh Bank Governor Atiur Rahman, in a letter, yesterday urged Inspector General of Police AKM Shahidul Haque to ensure trial of the policeman, who allegedly tortured an official of the central bank.

Atiur, in the letter, requested the IGP to ensure exemplary punishment for the sub-inspector after an investigation so that no BB official or general people become victims of torture in the future.

While talking to The Daily Star, BB General Manager AFM Asaduzzaman confirmed that the letter had been sent.

Golam Rabbi, an assistant director of the central bank, was tortured allegedly by police in the capital on Saturday night.

According to the victim, Sub-inspector Masud Shikder of Mohammadpur Police Station and his team beat him up for Tk 5 lakh on Tajmahal Road. The SI also threatened to kill Rabbi in "crossfire" and falsely implicate him in a narcotics case. Masud was closed on Monday.

Meanwhile, the traumatised BB official was admitted to Dhaka Medical College Hospital on Tuesday with pain in the head and shoulder.

The victim's relatives said a psychiatrist would visit Rabbi today, who could not sleep properly.

Rabbi said he filed a written complaint with Mohammadpur Police Station on Sunday and would file a case after getting released from the hospital.

Hafiz Al Faruq, assistant commissioner (Mohammadpur),  said he was investigating the incident.
