Fusako Shigenobu, the founder of the Japanese Red Army and a key figure in a series of international terrorist incidents in the 1970s, was arrested Wednesday in Osaka Prefecture.

Specifically, the arrest is over Shigenobu's role, along with two others, in seizing the French Embassy in The Hague on Sept. 13, 1974.

Shigenobu is believed to have been the mastermind behind the attack.
