The Police commissioner urged the residents to disregard the order and added that police would not allow such order to stand in the state.
IPOB recently announced September 14 as a remembrance day for the Biafran heroes and gave a sit-at-home order in the South-East.
The Police commissioner said security agencies would begin “a show of force” in the state on Tuesday to send a warning signal to the IPOB members.
“We are ready to stop the IPOB order; we will not tolerate it and I urged members of the public to go about their normal business.
“Police is there to ensure that maximum security is provided for members of the public,” he said.
