Abubakar Jimoh, the Deputy Director, Public Relations, confirmed the incident.
He said that the fire started around 7p.m. at the warehouse where fake and counterfeit products are kept.
"It happened in the warehouse where we keep fake and counterfeit products,’’ Jimoh said.
He said the fire might have been caused by an electrical fault as was the case in an earlier incident.
"As I speak with you we are trying to overhaul the entire electrical system in the office,’’ Jimoh said.
