Prosecutors said Saturday that a woman, identified in Japan as the leader of the terrorist Red Army, was a suspect in a car bombing that killed five people at a club for U.S. military personnel.
The chief investigator also said authorities were still searching for another Japanese terrorist and a man from the Middle East or North Africa.Investigators said they believe all three have fled the country.
FBI experts arrived to examine the explosives used in the bombing Thursday night that killed an American servicewoman and four Italians at the USO in downtown Naples.
A funeral service was held Saturday for one of the Italians, a 65-year-old souvenir salesman who was working his usual spot in front of the club when the bomb exploded. American sailors had affectionately called him Popeye.
Two Islamic groups claimed responsibility for the attack.
On Friday, investigators identified Junzo Okudaira of the Japanese Red Army, which has links to terrorist groups in Lebanon, as the man who parked the car in the narrow street that runs past the club. He had rented the car under a false name a few days earlier.
Romano Argenio, head of the Naples anti-terrorist police, said Saturday that investigators had identified one of Okudaira's accomplices as Fusako Shigenobu, 42, another known member of the Japanese Red Army.
Akio Ohno, an expert on the Red Army and a former student leader, said in Tokyo on Saturday that Shigenobu leads the Red Army. Ohno said Shigenobu had worked as a bar hostess in Tokyo to raise money for the terrorist organization.
A witness reported seeing Shigenobu and Okudaira together in Garibaldi Square at 11 a.m. Thursday, about nine hours before the explosion, Argenio said.
