Tsutomu Shirosaki, a former Japanese Red Army member involved in a deadly 1986 rocket attack on the Japanese Embassy in Jakarta, died in Tokyos Fuchu Prison on July 20 after choking on his food during dinner, sources said.

Shirosaki was 76 years old.

While still serving time for robbery and other crimes, Shirosaki was released from prison in 1977 as an “extrajudicial measure” by the Japanese government after the so-called Dhaka Incident in which JRA members hijacked a Japan Airlines aircraft and demanded the release of detainees.

He was later captured and sentenced to 30 years in a U.S. prison for a rocket attack on the U.S. Embassy in Jakarta that was staged simultaneously with the one on the Japanese Embassy.

In 2015, after his release, he was arrested on arrival in Japan by Tokyo police and sentenced to a prison term for attempted murder and other crimes over the Jakarta Incident.
