Late last year, five students gang-raped and beat a young woman at Abia State University in Nigeria, then passed around an hour-long video of their abuse for friends to watch. For months, Nigerian officials ignored the horrifying case and the governor of Abia state denied the attack even happened there.

But after more than 90,000 people signed Adetomi Aladekomo’s petition on Change.org to hold the rapists and government officials accountable, Nigeria’s Attorney General demanded that the Inspector-General of police open a formal investigation.

Now, though, local activists are scared that the investigation is stalling. They’re calling for more international pressure to make sure the investigation actually happens.
