Police said Monday they have arrested a woman and a man and are looking for three or four others in connection with the apparent kidnapping of a woman in Kokubunji, Kagawa Prefecture, last month and the extortion of 600,000 yen.

Following the arrest of Tomoe Choki, 33, on Sunday, 38-year-old Yoshitaka Kabashima was arrested Monday evening on suspicion of kidnapping the 22-year-old woman on a street in Kokubunji on June 29.

The kidnapped woman, the daughter of a businessman, was found safe by her 57-year-old father at a hotel in Fukuyama, Hiroshima Prefecture, on June 30 after he was contacted by the abductors, police said. Neither the victim nor her father were named.

Choki, of Hikari, Yamaguchi Prefecture, told police after her arrest, "We did not care who we kidnapped, as long as it was a family member of a business executive."
