The lady was said to have set the building on fire after successfully resisting several attempts to move her to a psychiatric hospital.
Residents of Bigard Seminary Avenue, the scene of the incident, were seen scampering for safety.
It was observed that the fire affected the last floor of the building and would have spread to the entire house and adjoining buildings if not for the alarm raised by the residents.
The fire was put out by men from the State Fire Service, who arrived before it spread to other nearby buildings.
It was learned that the lady's parents had attempted to send her to a psychiatric hospital when her mental illness started back in 2017.
The young lady, who lived with her parents on the last floor of the two-story building, started causing trouble lately, a development that forced her parents to invite policemen to help take her to the hospital.
A tenant who narrated what led to the incident said that trouble started when the parents invited some policemen to help bring the lady down from their flat to a psychiatric hospital.
"When the policemen came early this morning and the lady noticed that she was about to be taken away, she took the gallon containing fuel and poured the content everywhere."
"When the policemen climbed up the building, the lady lit up the place."
"Her parents, who were coming up with the policemen and the cops themselves, all ran for their lives."
"Her mother’s shout of fire! helped us know that something was wrong.
"However, men from the Enugu State Fire Service arrived quickly and extinguished the fire that had already consumed the two flats."
"The firemen were able to save the entire building from burning completely," a neighbour said.
The State Chief Fire Officer, Enugu State Fire and Emergency Service, Okwudili Ohaa, who confirmed the incident, said firefighters fought gallantly to quench the fire when they got to the scene.
He said that they were able to put out the fire with three fire trucks because getting to the place wasn't a big problem.
"At about some minutes past 6 a.m. today, Thursday, 11-11-2022, we received a distress call of a fire outbreak in a two-story residential building at Bigard and Zik Avenue, Uwani.
"We sent two, three trucks and firefighters to the fire."
"The fire was fought, controlled, and extinguished with the assistance of the public, who were at the scene before our arrival."
"Although the fire affected the last floor of the building, a lot was saved within and around the burning building."
"The fire affected the other flat because it was caused by gasoline."
"They said it was a mentally deranged lady who started the fire."
The lady was later rescued from the burning fire and taken to the Enugu Neuropsychiatric Hospital for treatment.
