"I cannot fold my hands and watch this lawlessness," he said in a statement Monday.

"Information reaching us is that too soon dangerous elements will join the groups under the guise of protest and detonate explosive(s) aimed at embarrassing the government. Accordingly protests on the Chibok Girls is hereby banned with immediate effect," the commissioner continued.

More than 200 schoolgirls were kidnapped in northern Nigeria in April by Boko Haram, in an act that drew international condemnation.

The terror group abducted an estimated 276 girls on April 14 from a boarding school in Chibok. Dozens escaped, but more than 200 girls are still missing.

Nigerians and others have accused their government of not acting swiftly or efficiently enough to protect the girls seized in the dead of night.

Boko Haram translates as "Western education is a sin" in the Hausa language. The militant group says its aim is to impose a stricter enforcement of Sharia law across Nigeria, Africa's most populous nation, which is split between a majority Muslim north and a mostly Christian south.
