Georgian prosecutors on Friday charged a man with premeditated murder in the killing of a policeman who tried to arrest him on suspicion of throwing a grenade during a rally by President Bush in Tbilisi in May.
A spokeswoman for the Georgian prosecutor's office, Khatuna Khvediashvili, said Vladimir Arutyunian, 27, had been formally presented with the charge. Arutyunian was detained after a deadly shootout with security forces on Wednesday in which a policeman died.
Both Mr. Bush and Georgian President Mikhail Saakashvili were on the podium in downtown Tbilisi when the grenade was thrown and landed about 100 feet away. The grenade did not explode and nobody was hurt.
Arutyunian admitted to throwing a grenade while in the hospital, where he is being treated for wounds suffered during his deadly shootout with police.
There was no immediate indication from authorities whether he was connected to any separatist groups in Georgia's breakway region of Abkhazia or nearby Chechnya.
Video released Thursday by Georgian authorities showed the suspect lying on a gurney being wheeled from the scene, one of his cheeks swollen and bloody. He made an obscene gesture at the camera.
A preliminary investigation indicated the activation device deployed too slowly to hit the blasting cap hard enough, the FBI said.
In a statement Thursday, the U.S. Embassy in Georgia said it "welcomes the news that the Georgian Ministry of Internal Affairs, through joint efforts with the Federal Bureau of Investigation, diligent detective work and a strong commitment to solving this case, have taken into custody a suspect." But the embassy declined comment on whether the FBI was involved in the arrest or follow-up.
Georgian authorities had released a photo Monday of the suspect and announced a reward of about $80,000 for information leading to his identification.
Officials on Thursday were giving little information about Arutyunian, described in news reports as being in his mid-20s and unemployed. But Interior Ministry spokesman Guram Donadze said grenades and unspecified chemicals were found in a search of Arutyunian's residence.
The video showed police sorting through a pile of items apparently found in his apartment, including a book called "Initial Military Training" that was part of the standard curriculum in Soviet schools.
Georgian officials initially claimed the grenade had not been set to explode, and U.S. officials said Mr. Bush had been in no danger, but officials they later said the grenade had been a threat to the president's life.
The FBI statement contradicted the reports and identified it as a live hand grenade, whereas initial Georgian statements said it appeared to have been an "engineering grenade," a device that is not designed to spread shrapnel.
Mr. Bush spoke from behind bulletproof glass as he addressed a huge crowd in a main Tbilisi square as part of a visit aimed at cementing relations between the United States and Georgia's new pro-Western leadership.
Saakashvili, who came to power after the 2003 Rose Revolution that ousted Eduard Shevardnadze, has provoked enmity with his anti-corruption initiatives and insistence on restoring control over two separatist regions.
