South Korean police say they want to talk to the wife of the Belgian ambassador there, after an incident in which she allegedly slapped a shopkeeper.
Footage from a security camera emerged online this week from a clothing store.
It shows a woman slapping a shopkeeper who had tried to stop her from approaching another worker.
They had suspected she was trying to leave the shop with an item of clothing she had not paid for.
Police who were dispatched at scene identified her as Xiang Xueqiu, the wife of the Belgian ambassador, according to an officer at the local police station. Police say they received a complaint over an alleged assault.
But since then, the police have not been able to contact Xiang, saying it was because she was in a hospital.
Reuters was unable to identify which hospital and could not immediately reach her for comment.
The Belgian embassy in Seoul confirmed Xiang had been hospitalized but made no further comment.
South Korea's foreign ministry told Reuters it had urged the Belgian embassy to cooperate on the matter and said it would take appropriate measure based on the police investigation.
