Acting on an anonymous telephone call, Georgian antiterrorist police raided a building in the suburbs of Tbilisi late on 20 July where the man who allegedly threw a hand grenade at U.S. President George W. Bush during his visit to Tbilisi two months ago was believed to be hiding. The suspect was wounded, and one antiterrorism squad officer killed, in an exchange of fire. The suspect escaped but was tracked down and apprehended two hours later. He has been identified as Vladimir Arutiunian, 27. Arutiunian has been hospitalized and has reportedly confessed to throwing the grenade, saying: \"I would do it again.\" Police searched the basement of Arutiunian\'s home and confiscated hand-made detonators, grenades, maps of Tbilisi, and \"biological and chemical substances.
