Police in Nigeria are investigating the rape and murder of 18-year-old student, Barakat Bello.

She was killed on Tuesday in the south-western state of Oyo.

The case is just one in a string of violent sexual attacks and murders of women in Nigeria in the space of a week.

Ms Bello, who was a student at the Federal College of Animal Health, had returned to her parents’ house because of restrictions put in place to stop the spread of Covid-19.

On Tuesday, she was at home alone. But when her younger brother returned he found a pool of blood close to the bathroom.

Investigations revealed she was raped and murdered.

In the past week there has been widespread anger on social media as many Nigerians say they are concerned about the government's unwillingness to tackle gender-based violence.

On Sunday, 12 men in the north-western state of Jigawa were arrested following allegations connecting them to the rape a 12-year-old over a two-month period.

Last Tuesday, 16-year-old Tina Ewekwe, was shot dead by a policeman in Lagos.

Authorities say two officers are in custody.

In the same week 22-year-old Uwavera Omozuwa was murdered in a church - her sister says she was also raped.

On Tuesday, Nigeria’s President Muhammadu Buhari condemned the murder of Ms Omozuwa.
