Here's the news story about Bautista's arrest.
A Mexican chemistry student accused by police of plotting a gas attack on anti-papal protesters said he only meant it as a "joke" and has been released from jail, a court said Thursday. Spain's National Court said in a written ruling that 24-year-old Jose Alvano Perez Bautista's comments on an Internet page could result in charges of making aggravated or even terrorist threats. The student, who was among 30,000 volunteers for World Youth Day celebrations led by Pope Benedict XVI, is accused of making threats on a page of online newspaper La Voz Libre (The Free Voice). Spanish police had originally accused him of actually plotting a gas attack on the protesters. "Obviously, this is a reduction in the level of crime because they did not find elements that could constitute hazardous tools for action," Mexican embassy spokesman Bernardo Graue told AFP.Bautista claims that his threats were only meant to incite fear and reduce attendance at the anti-Pope protests. He is a volunteer organizer for the Pope's visit.
