Police sent investigators to Britain on Sunday to look into the case of a Japanese woman who went missing in Europe in 1983 and was allegedly abducted to North Korea.

Investigators from the Metropolitan Police Department and the National Police Agency will also visit Denmark and Croatia after Britain to seek the cooperation of local investigative authorities in the case of Keiko Arimoto, a former student at Kobe City University of Foreign Studies who was 23 when she vanished, police said.

Earlier this month, police asked for information from Arimoto's host family in London, where she studied, and asked British authorities to provide them with documentation such as copies of her arrival and departure records.
