A former minister and convener of the BringBackOurGirls (BBOG) group, Oby Ezekwesili, has been arrested and is being detained by the police in Abuja.
In series of posts on her Twitter handle, @obyezeks, the former Minister of Education, said she was arrested alongside some members of the BBOG group.
Her arrest is believed to be connected to the activities of the group.
More than 100 girls are still missing after they were abducted from their school in the north-east Nigerian town of Chibok in 2014 by militant group Boko Haram.
The group has continually demanded that President Buhari fulfills his promise by rescuing the girls.
According to her, Aisha Yesufu, Ms Maureen Kabrik, Jeff Okoroafor and four others were also arrested.
Ezekwesili tweeted: “The FG of President .@MBuhari instructed the IG of @PoliceNG to DETAIN ME AND OTHER MEMBERS of @BBOG_Nigeria here at the Unity Fountain. Police men and women have BUILT AN IMPREGNABLE WALL and LOCKED ME IN. I have asked them more than 30 times to LET ME OUT and they REFUSED.
“President @MBuhari The police officers deployed by IG of .@PoliceNG is VIOLATING my FREEDOM of MOVEMENT by LOCKING ME IN in broad day light at the Unity Fountain. THIS IS A DEMOCRACY. Officer Tina Ishaya just again REFUSED TO LET ME OUT OF THEIR WALL.
“President @MBuhari at your instruction, the IG of @PoliceNG CONTINUES TO DETAIN ME and HAVE ARRESTED SOME OF OUR MEMBERS.
“President .@MBuhari members of our BBOG Movement @BBOG_Nigeria HAVE BEEN ARRESTED BY OUR IG of .@PoliceNG . WE ARE ALL WAITING TO BE ARRESTED SINCE it has become an OFFENSE to DEMAND THAT YOU KEEP YOUR PROMISE TO RESCUE ALL OUR CHIBOKGIRLS.
“I have been ARRESTED along with rest of our BBOG members and NOW DETAINED without a charge by the .@PoliceNG . WE are detained at the FCT command . The Police here has REFUSED to tell us why we are DETAINED.
What Are WE Demanding?
Reacting to the reported arrest, The Socio-Economic Rights and Accountability Project, in a statement via its Twitter page, demanded the immediate release of those arrested.
SERAP tweeted, “The reported false imprisonment & detention of @obyezeks & members of @BBOG_Nigeria makes a mockery of @MBuhari’s claim that this govt is one of change that is governed by d rule of law. The authorities should immediately release them & allow them to freely exercise their rights.”
