The cause of an apartment fire that killed three and injured dozens more in Uijongbu is being blamed on something as stupid as this:

An arrest warrant has been requested for a 53-year-old man who allegedly caused a massive fire at an apartment building in a Seoul suburb that killed four people and injured scores of others, police said Tuesday.

The man, identified only by his surname Kim, faces charges of manslaughter, assault without intent and causing a fire without intent, the Uijeongbu Police Station in this city just north of Seoul said.

Police believe the fire at the 10-story Daebong Green Apartment on Jan. 10 started when Kim held a flame up to the ignition of his motorcycle parked outside the apartment. He reportedly did this to take out the key that had frozen inside the ignition.

What Kim did not notice, however, was that he was also melting the sheaths of the ignition line, which created a spark and quickly developed into an inferno that injured 126 people, police said.  [Yonhap]
