Recalling the explosion at a bar in Mubi, Adamawa, on Sunday, Olukolade urged the fans and citizens to always take notice of strange persons or objects around them.
He also advised them to report strange objects to security agencies for prompt action to forestall untoward incidents.
Olukolade said a key suspect in the explosion which rocked the bar, had been arrested.
He confirmed that 18 people died while 19 sustained in injuries the explosion.
He said military operations were being intensified in the North East and other areas where there were crises.
Olukolade said troops in crisis areas of Benue killed five terrorists, recovered riffles and two vehicles when they engaged troops during routine patrols.
According to him, security agencies are working round the clock and sharing information with their foreign partners in the effort to rescue the kidnapped school girls.
He, however, appealed to the media and citizens to be moderate in their speculations and conclusions on efforts to rescue the girls.
Olukolade said such speculations were not helping the operations.
