Police arrested an 18-year-old female college student Friday on suspicion of abducting a 6-month-old baby girl who was found seven hours after going missing in Saitama Prefecture on Aug. 3, police officials said.

The suspect, who lives in the prefecture, was not identified because she is a minor.

The baby, named Yuka, went missing around 11:15 a.m. Aug. 3 when her mother, Keiko Kurabayashi, 23, went shopping and briefly left her alone in a minivan in the parking lot of a shopping center in Higashi-Matsuyama, Saitama Prefecture.

Yuka was found unharmed in a car parked at a supermarket about 2 km away from the shopping center shortly after 6 p.m., when the car's owner returned from shopping. The baby had a fresh diaper on when she was found.
