Nigeria authorities have arrested more than 800 suspects in connection with incidents of arson, looting and killings across the country.
At least 520 suspects were arrested in Lagos alone.
Angry youths have been targeting government warehouses across the country believed to be housing food items meant to be distributed as Covid-19 relief.
On Tuesday, a group, armed with knives and other weapons, broke into the orientation camp of the National Youth Service Corps in the capital, Abuja, carting away mattresses and other goods.
The looting and arson attacks followed peaceful protests against police brutality that had rocked Nigeria.
