On Friday the federal government has ordered Mohammed Adamu, Inspector General of Police, to provide security for the 17 Edo All Progressives Congress (APC) lawmakers.
Abubakar Malami explained that the directive became necessary to prevent breakdown of law and order.
The APC legislators are loyal to former national chairman, Adams Oshiomhole, and the governorship candidate, Osagie Ize-Iyamu.
On Thursday, they clashed with lawmakers loyal to Governor Godwin Obaseki.
Obaseki has vowed to deal with perpetrators of violence.
He indicted Oshiomhole, his predecessor, for the Edo Assembly change of leadership and turmoil in the state.
