A section of the Rivers State Secretariat was on Monday evening gutted by fire, leaving parts of the complex damaged before it was brought under control.
The fire, which reportedly started a few minutes past 5 p.m., was contained through the swift response of the Rivers State Fire Service.
Eyewitnesses said the blaze spread rapidly before firefighters arrived at the scene to extinguish it, preventing further damage to nearby offices.
Although the cause of the fire has not been officially confirmed, preliminary reports suggest that an electrical fault may have triggered the incident.
The Rivers State Head of Service, Inyingi Brown, also attributed the outbreak to an electrical fault, urging workers to ensure that all electrical appliances are switched off before leaving the office.
An unconfirmed source indicated that the fire may have affected the state Pension Commission, though the extent of the damage remains unclear.
Authorities are yet to release an official statement on the full impact of the incident as investigations continue.
