Francisco Javier Lopez Pena, leader of Basque separatist group ETA, shouts slogan as he leaves the house where he was arrested by French police earlier in Bordeaux, southwestern France, May 22, 2008. The leader of Basque separatist group ETA has been arrested in what Spanish officials described on Wednesday as a heavy blow to the guerrilla group and its bombing campaign in Spain. Pena, also known as Thierry, and three other ETA leaders were arrested by French police in a raid in the centre of the southwestern city of Bordeaux late May 20, 2008, a police source said.
