The family of a pilot who was slain in the July 1999 hijacking of an All Nippon Airways airliner filed a damages suit Friday for 280 million yen against the government, the airline and the hijacker, the family's lawyer said.

The family of Naoyuki Nagashima, who was stabbed to death by the hijacker, accuses the government of failing to step up security at Tokyo's Haneda airport even though the hijacker had sent several warnings before the incident.

The suit, filed with the Tokyo District Court, is the first in Japan seeking to pin responsibility on the government for an airplane hijacking.
