A car with Chiba Prefecture license plates was seen parked in front of Aum Shinrikyo's Nagoya chapter building about 12 hours after a woman was set free in the city after being abducted in Narashino, Chiba Prefecture, investigative sources said Thursday.

The victim, a 19-year-old college student, is the sister of a teenager killed in the 1994 nerve gas attack in Matsumoto, Nagano Prefecture.

She was freed in Nagoya uninjured, 12 hours after her abduction from the street outside her home, according to police.
