The protesters are demanding better governance in Nigeria, an end to corruption and improvement in the security and welfare of citizens.
The actions of the security agencies have been condemned by civic groups and many Nigerians.
In Lagos, journalist Agba Jalingo and 18 other protesters who were arrested during the protest were released Wednesday evening.
“They were taken from Area F to Ikeja police command and were subsequently taken to mobile court, and all of them were discharged,” .
