Venezuelan opposition chief surrenders but not without a rally

CARACAS, Venezuela — A prominent Venezuelan opposition leader surrendered to the authorities on Tuesday in the midst of a large crowd of supporters who tried to block his arrest on accusations that he was responsible for violence that erupted during recent antigovernment protests.

Before giving himself up, the opposition politician, Leopoldo López, walked through a sea of thousands of supporters in the largest rally in more than two weeks of growing protests fueled by discontent over runaway violent crime, a stalled economy, government pressure on the news media and other issues.
