The commissioner said the prior approval requirement was intended to allow security agencies to assess potential risks and prevent activities that could threaten public safety.
He also warned individuals against provocative statements, threats and inflammatory comments circulated on social media, particularly those capable of influencing followers to engage in actions that could threaten peace.
Bakori said security agencies were monitoring such developments and would take action within the law where comments or conduct crossed the line into criminal activity or threatened public order.
The commissioner said the police and other security agencies remained committed to protecting lives and property, maintaining public peace and ensuring that lawful directives were obeyed across Kano State.
The five arrests mark one of the first publicly disclosed enforcement actions linked to the reported destruction of political campaign materials amid the latest security tensions in Kano.
The police warning also places renewed emphasis on prior security clearance for public horse-riding activities as authorities seek to prevent further escalation arising from competing political, traditional and public-order interests in the state.
