# Suspected arson at Seoul apartment block kills one and injures six
One person was killed and six others injured on April 21 after an apparent arson attack at a 21-story apartment building in Seoul's Bongcheon-dong neighborhood. Police said the fire broke out on the fourth floor at 8:17 a.m., and that the man suspected of starting it, who was in his 60s, was later found dead in the hallway on the same floor. The case was immediately treated as a criminal investigation rather than an accidental blaze.
Firefighters and police said two residents in their 70s and 80s plunged to the first floor with full-body burns, while four others were taken to hospital after complaining of breathing difficulty. The fire was extinguished nearly an hour and 40 minutes after the first report, but by then the building had already become a major emergency scene in Gwanak district. The casualty count also suggests how quickly smoke and flame can move through a high-rise residential block.
Investigators said they found a note inside the suspect's residence and were looking into the exact motive. They also believed he may have poured oil into a pesticide applicator before starting the fire. Those details are preliminary, but they point to a deliberate act rather than a simple electrical fault or cooking accident. The arrest scene itself never developed because the suspect was found dead, leaving police to reconstruct the sequence from evidence inside the apartment and the testimony of surviving residents.
The response involved multiple layers of emergency work: firefighters, police and building personnel, plus a medical response for people who had fallen or inhaled smoke. The excerpt does not say how many residents had to be evacuated, but it does show the scale of the disruption. A high-rise apartment block in a dense city means even one floor can send smoke through stairwells and hallways quickly, especially when the fire is deliberately set and the initial call reaches responders only after flames are already moving.
Seoul has seen many residential fires over the years, but this one stands out because of the apparent intent behind it and the fact that the suspect died at the scene. For the residents who were injured, the immediate question is survival and recovery. For police, the challenge is motive: why the man chose that building, why he appears to have used an oil-soaked applicator, and what the note found inside his residence says about his state of mind. Those answers will determine how the case is ultimately classified.
The suspected arsonist's death complicates the investigation even further because police cannot question the person they believe started the fire. That leaves the note, the hallway death and the building evidence as the main sources of information. The source says investigators think he may have poured oil into a pesticide applicator before igniting the blaze, which suggests deliberate preparation rather than an impulsive act. If confirmed, that detail will matter for how the crime is classified and how investigators explain the spread of fire on the fourth floor.
The injuries show why the scene became so dangerous so fast. Two residents fell to the first floor with full-body burns and four others reported breathing difficulty, which means the fire was not limited to one apartment unit. A high-rise building has stairwells, hallways and ventilation paths that can spread smoke quickly, and that is likely why responders needed nearly an hour and 40 minutes to extinguish the blaze. The article does not say whether the building was evacuated floor by floor, but the casualty pattern makes clear that smoke inhalation was a major part of the harm.
For police, the note found in the suspect's residence is likely to be one of the most important pieces of evidence because it may explain motive, grievance or planning. Until that is decoded, though, the safest reading is simply that a man in his 60s appears to have started a fire, died at the scene and left six other people injured in a residential tower. The source packet is specific enough to support that conclusion and careful enough not to go beyond it.
