Six relatives of Japanese radicals who hijacked a Japan Airlines plane to North Korea in 1970 arrived in Japan on Tuesday night, five of them children of the hijackers who were born and raised in the communist state.
At Narita airport, police arrested Takako Konishi, 56, wife of Red Army Faction group leader Takahiro Konishi, on suspicion of violating the passport law, officials said.
The other five are Konishi's 22-year-old daughter and the children of four other hijackers: two men and two women aged between 22 and 25.
Japanese police put Takako Konishi on an international wanted list in 1993 after she refused to surrender her passport. Tokyo ordered her to do so for allegedly making contact with North Korean intelligence agents in August 1988.
