Student 'Twitters' his way out of Egyptian jail

Buck, a graduate student from the University of California-Berkeley, was in Mahalla, Egypt, covering an anti-government protest when he and his translator, Mohammed Maree, were arrested April 10.

On his way to the police station, Buck took out his cell phone and sent a message to his friends and contacts using the micro-blogging site Twitter.

The message only had one word. "Arrested."

Within seconds, colleagues in the United States and his blogger-friends in Egypt -- the same ones who had taught him the tool only a week earlier -- were alerted that he was being held.
