SEOUL, South Korea (AP) — A woman was arrested in South Korea on Thursday on two murder charges from New Zealand, where the bodies of two long-dead children were found last month in abandoned suitcases, authorities said.

Authorities didn’t immediately say if the 42-year-old suspect was the dead children’s mother. New Zealand police had earlier told their South Korean counterparts that the mother might be living in South Korea.

South Korean police detained the woman in the southeastern port city of Ulsan, based on a South Korean court warrant issued after New Zealand requested her provisional arrest as part of an extradition process, according to South Korea’s National Police Agency and Justice Ministry.

The unidentified woman covered her face with the hood of her coat as officers escorted her outside an Ulsan police station and put her in a car headed for the capital, Seoul, where she was expected to be questioned by prosecutors.

New Zealand authorities must submit the formal request for her extradition to the South Korean Justice Ministry within 45 days. The ministry will then decide whether to proceed with an extradition review at the Seoul High Court to rule whether she would be sent to New Zealand.
