A 21-year-old Japanese university student is missing in France, and local police are trying to ascertain the whereabouts of another foreign student in connection with her disappearance, local authorities and media said Friday.

Narumi Kurosaki, a Tokyo-born student at the University of Tsukuba in Ibaraki Prefecture, began attending the University of Franche-Comte in Besancon, eastern France, in September to study language, according to the authorities and other sources.

Kurosaki disappeared around Dec. 4 and could not be reached on her cell phone thereafter, they said. Her credit card has also been suspended. On the night of Dec. 4, just before her disappearance, she had a meal with acquaintances at a local diner, including the man the police are now trying to locate.

The police have released her photo to seek information from the public. They have also notified their EU counterparts in search of the man, according to the local media.
