Tension was high as security personnel moved in immediately and cordoned the court precincts and evacuated members of the public, court staff together with suspects who had appeared for mention and hearing of their cases.
Senior Principal Magistrate Dennis Mikoyan however said that those who planted the two bags outside court corridors just wanted to disorganise the day’s activities.
Police led by Nyandarua County Commander Hamisi Mabeya led the operation.
Bomb experts however later ruled out the presence of explosives.
Previously, the courts have dealt with two cases of people being arrested with explosives and one charged with being a member of the Al Shabaab militia.
The government has urged the public to remain vigilant as the country deals with increased terror threats.
Mikoyan however said it was good for the public to be alert as this could save lives.
