Police are under fire for failing to prevent a murder after arriving at the crime scene belatedly because they mistook two similar cases as one.
Officials at Yongsan Police Station in Seoul said Monday that they detained a woman, surnamed Park, 64, on suspicion of killing her son's girlfriend.
According to police, Park and the girlfriend, Lee, 34 who had long been at odds over several issues, quarreled over the phone on Saturday evening. Lee then came to Park's house to confront her.
Park allegedly waited in front of the house in Hannam-dong with a knife.
While quarreling there, Lee allegedly threw her purse at Park and Park then stabbed Lee in the stomach at 9:42 p.m.
Park had been on medication for depression and bipolar personality.
Before the argument, Park's son, who feared there might be bloodshed, called police at 9:12 p.m. about 30 minutes before the stabbing, saying his mother was waiting for Lee with a knife.
Yongsan Police Station asked patrol officers to visit Park's house, but the officers confused the case with a similar case of domestic violence nearby. The call for that case was reported 10 minutes earlier.
The house was about 68 meters from Park's house. The police spent the time for that call at the different house.
Park's son made a second call 15 minutes later at 9:27 p.m., urging police to come immediately. But the patrol officers still thought it was for the other case.
The officers finally noticed that the two were separate cases when looking at the reports closely at 9.37 p.m.
They tried to go to Park's house, but were stuck in traffic, so other patrol officers nearby arrived at 9:51 p.m., minutes after the stabbing.
Lee was rushed to a nearby hospital, but she bled to death.
Officials at the police station apologized for the incident, saying the death was a result of their misjudgment.
"Because police should protect people's lives, it is regretful that it took 30 minutes for officers to arrive at the scene after the emergency call, whatever the reasons might have been," an official said. "We express our deepest condolences to the deceased's family."
Police are questioning the officers involved.
Police will ask the prosecution for an arrest warrant for Park on a murder charge.
