Former prime minister Sheikh Hasina has been sued in four more cases over the killings of three people and the attempted murder of another person during the student-led mass uprising.

Three of the cases were filed with Dhaka courts yesterday while another murder case was filed in Bogura two days ago.

Several former ministers, including Awami League General Secretary Obaidul Quader, Asaduzzaman Khan, top police officers and at least three journalists, were among the accused.

With these, Hasina is now facing 75 cases related to the protests, including 63 on murder charges, seven on allegations of crimes against humanity and genocide, three on charges of abduction, and two for other charges.

Hasina and 30 others were sued over the death of grocery shop owner Mizanur Rahman during the quota reform movement in the capital's Banasree on July 19. His father Kamal Hossain filed the murder case with the court of Additional Chief Metropolitan Magistrate Md Tofazzal Hossain who asked Khilgaon Police Station to register it as a first information report (FIR).

The court asked the OC of the same police station to register an FIR over the death of 14-year-old Ashiqul Islam on the same day. Hasina and 26 others were accused in the case filed by Ashiqul's mother Arisha Afroz.

The third case was filed against Hasina and 50 others on charges related to the attempted murder of a lawyer of the Dhaka Bar Association during the students' quota reform protest on July 18.

Advocate Abdul Baset Shamim filed the case with the court of Additional Chief Metropolitan Magistrate Md Tofazzal Hossain. The magistrate asked Mugda Police Station's OC to register the complainant's statement as an FIR.

In Bogura, Hasina, three local journalists and 130 others were sued in a murder case over the death of Md Shaheed, 35, who was shot dead on August 4, a day before Hasina's fall.

Shimu Begum, 34, the wife of the deceased, filed the case on Tuesday, said Bogura Sadar Police Station OC Saihan Olliullah.
