The National Security Adviser, Babagana Monguno, said 52 cases of electoral violence have been recorded in 22 states in one month.
This was as he warned political parties to caution its officials and supporters, noting that perpetrators would not be spared.
Monguno gave the warning during an emergency meeting of the Inter-Agency Consultative Committee on Election Security on Friday.
The NSA said that the President, Muhammadu Buhari , was committed to ensuring a free and fair election. Hence, a directive has been given to security agencies to be on guard to avert any attack and arrest perpetrators.
Speaking at the event, the Chairman of the Independent National Electoral Commission, Mahmood Yakubu, stated that the uncollected 65,699 Permanent Voters Cards burnt in its office in Ogun State would be replaced, and its staff would be relocated.
