The fire, which was said to have been started in the early hours of Tuesday, affected the library and security posts of the building.
A source told The Nation the attack was carried out by hoodlums using fire bombs.
However, fire fighters were said to have been later mobilised to the scene and helped to put the fire out before it could cause further damage.
Spokesman of Ebonyi Police Command, Loveth Odah confirmed the incident.
She said the attackers came in their large numbers to carry out the attack on the court. (The Nation)
