Two male and female guests at a motel in Uijeongbu City, Gyeonggi Province, were seriously injured due to carbon monoxide poisoning. On the 30th of last month, after the first 112 report, police visited and confirmed that the guests were sleeping before withdrawing. However, after receiving a second report the next day, police who revisited the scene found the guests unconscious and collapsed. The guests are currently in critical condition, and police are investigating the cause of the gas leak and whether the initial police response was appropriate.
