A man killed his neighbor in another case of fatal noise-related conflict in apartment complexes, Seoul police said Sunday.

The Dobong District police are investigating a 54-year-old man surnamed Cho for the alleged murder of his neighbor at an apartment in Chang-dong.

According to the police, Cho, who lives on the 12th floor of the building, went to the floor above around 9 p.m. to complain about the noise.

Cho and the victim, a 48-year-old man surnamed Jin, then got into a physical altercation, after which Cho went downstairs to his apartment to fetch a weapon and stabbed Jin in the abdomen.

The victim was transported to a hospital, where he died.

Jin had been visiting his mother’s apartment for an ancestral worship ceremony when the incident took place. He had previously been living with his mother, but moved to a nearby building after he fought with Cho on noise issues. The police are seeking an arrest warrant for Cho.

The incident marks another death in a string of violent clashes over noise levels between apartment floors.

In May 2013, a 73-year-old man killed two people by setting fire to their apartment, and in February, a 46 year-old man stabbed two brothers to death.
