There is outrage in Nigeria following the murder of a 22-year-old student, Uwavera Omozuwa in a church.

The hashtag #JusticeForUwa is trending in Nigeria, with her family appealing for help to track down her killers.

Uwavera had been studying in a "quiet" church near her home in Benin City when she was killed, her sister, Judith, told BBC Pidgin.

The student, who had wanted to become a nurse, died in hospital on Saturday, three days after the attack.

Judith Omozuwa said her sister had also been raped.

Her family said they received a call from a woman at the Redeemed Christian Church of God on Wednesday evening.

Uwavera was taken to hospital after a security guard found her, her skirt torn and her shirt covered in blood, Judith Omozuwa said.

'Failure to curb gender-based violence'

However, a police spokesperson in southern Edo State, whose capital is Benin City, told BBC Pidgin that they were treating the incident as a murder, not a rape, case.

The student died following a fight at the church, the spokesperson added, without giving more details.

Uwavera had only just been admitted to the University of Benin to study microbiology when she was killed.

She often went to sit and "read" at the church near her house as it was quiet, her sister added.

Unconfirmed reports in local media said a group of men had entered the church, raping Uwavera and hitting her with a fire extinguisher.

On Tuesday, many Nigerians were angered after a policeman allegedly shot dead a 16-year-old girl, Tina Ezekwe, in the commercial capital, Lagos.

The officer was arrested, police said.

On Twitter, many Nigerians expressed concern about the government's failure to tackle gender-based violence, and questioned whether parents were bringing up boys properly.
