Police on Wednesday served a fresh arrest warrant on a man they arrested last month after 45 years as a fugitive, suspecting he murdered a police officer during a riot by far-left activists in Tokyo.
The man, arrested by Osaka police on May 18 on suspicion of a separate offense, has not given his name but was identified by the police as Masaaki Osaka, 67, on Tuesday through multiple DNA tests.
Osaka is suspected of killing security police officer Tsuneo Nakamura, 21, on Nov. 14, 1971, when students and other activists protesting the ratification of a Japan-U.S. treaty on the reversion of Okinawa staged a violent riot in Tokyo's Shibuya district.
Osaka at the time was a member of the Japan Revolutionary Communist League National Committee, often referred to as Chukaku-ha, or "middle core faction."
He was put on the wanted list in 1972 for the charges of murder, assembling with weapons and assault along with other lesser charges.
His period on the run was the longest among major crime suspects designated by the National Police Agency. The police suspect the Chukaku-ha group has systematically supported him throughout the years.
As the trial of Osaka's alleged accomplice was suspended in 1981 due to mental illness, the statute of limitations for the murder case has not expired. The 15-year statute of limitations for murder was abolished in 2010.
Osaka was arrested for allegedly obstructing police duties when the police raided an apartment in Hiroshima used as a hideout of the Chukaku-ha while searching for a fellow activist.© KYODO
