Nigerian police say they have arrested two men wanted in connection with the gang rape of a woman whose ordeal was then posted on the internet.
The police commissioner in Abia state says the suspects were detained after cyber activists posted pictures and names online, the BBC reports.
The video has shocked Nigerians for the brutal nature of the attack and for the failure of police to do anything.
The arrests follow a sustained campaign by social network activists to force police to investigate.
Five men are believed to have taken part in the rape.
