Nigeria's Panels of Inquiry: One mother's long road to justice
After weeks of protests in Nigeria, several states across the country have set up Panels of Inquiry to investigate incidents of police brutality.
Many families are hopeful these panels will give them the justice they have been looking for.
Patience Mbang, whose son has been missing since his arrest in 2007, is one of them.
