Police Bureau of Investigation (PBI) Special Crime (South) on Tuesday arrested Saifa Rahman Mim, accused in a case over the rape and murder of college student Mosarat Jahan Munia, for interrogation from her Dhanmondi residence.

PBI Additional Superintendent of Police (Law and Media Branch) Md Abu Yusuf confirmed the matter to UNB.

On September 6 last year, Munia's sister filed a rape and murder case against the Bashundhara Group MD and seven others with Dhaka's 8th Tribunal for Prevention of Women and Children's Repression.

The court, after recording the complaint, directed the PBI to submit a report on it.

The seven other accused in the case are: Anvir's parents Bashundhara Group's Chairman Ahmed Akbar Sobhan Shah Alam and Afroza Begum, Anvir's wife Sabrina Sayem and model Faria Mahbub Piyasha, friend Saifa Rahman Mim and owner of the flat Ibrahim Ahmed Ripon and his wife Sharmim Akhter.

On April 26 of the same year, police recovered the body of the 21-year-old Munia hanging from a ceiling fan of her bedroom in a Gulshan flat.

Munia's elder sister, Nusrat Jahan Tania, filed a case against Anvir that night accusing him of incitement to suicide.

According to Tania, her sister, Munia, was in a relationship with Anvir who regularly visited her at the Gulshan apartment.
