Four teenage children of U.S. military personnel at Yokota Air Base in Tokyo were arrested Saturday on suspicion of attempted murder.
The arrests were made after a 23-year-old woman on a motorbike was seriously injured when she was caught in a rope stretched across a road, police said.
The Metropolitan Police Department arrested the four boys and girls, aged between 15 and 18, after the U.S. military handed them over earlier in the day, they said.
The police obtained arrest warrants for the four teens on Nov. 24, but the U.S. military did not immediately hand them over.
The woman was trapped in the rope, which was stretched across a road in Musashimurayama, Tokyo, about 1 km from the Yokota base, as she was riding a minibike late at night on Aug. 13. She was knocked off the bike and suffered a skull fracture.
According to the police, the victim and people in the neighborhood reported that they saw several foreigners before the incident, and the four were caught on a surveillance camera near the site.
