Twelve people were arrested in Tucson when a crowd of about 250 protested the international free trade summit Friday.
The protesters carried signs denouncing the North American Free Trade Agreement and the Summit of the Americas - a trade conference that opened Friday in Canada - where President Bush and other leaders debated a zone known as the Free Trade Area of the Americas.
As many as 20 people were initially detained, but some were cited and released. The 12 people arrested were booked into Pima County Jail on charges of unlawful assembly and blocking traffic, said Sgt. Judy Altieri, Tucson Police Department spokeswoman.
About 10 members of UA's Students Against Sweatshops participated in the demonstration, and none were arrested, said Jesse Kirchner, a linguistics sophomore and SAS member.
"The FTAA is basically the next step in globalization, and globalization is what sweatshops are all about," he said.
