The Abuja Police command has released the former Minister of Education and convener of the BringBackOurGirls group, Oby Ezekwesili after arrest and detention early on Tuesday in Abuja.
The police, however, refused to tell her and seven members of her group the reason they were arrested.
But the arrest might be connected to the activities of the group seeking a safe rescue of more than 200 girls were abducted from Government Secondary School, Chibok, in April
2014 by Boko Haram insurgents.
She said Aisha Yesufu, a known critic of the President Muhammadu Buhari-led administration and six others, were also arrested.
“Without stating the reason for our arrest and detention, Commissioner of Police at the FCT Command, CP Bello has asked us to be let out of their station,” she tweeted.
“We insisted on a formal charge and release but his response? “I am the commissioner and now release you to go.”
The former minister has also been criticising most of Buhari’s policies.
