Five of nine protesters arrested in April and accused of blocking Central Avenue during a large protest of Senate Bill 1070 pleaded guilty Wednesday to a misdemeanor.

They were sentenced to time served, according to one of the protesters. A sixth protester was found guilty by a judge. His sentence was unknown.

Each spent the night in jail following the arrests on April 25, the same day the U.S. Supreme Court heard arguments on Arizona's immigration law, known as SB 1070.

They were among about 500 people who blocked Central Avenue for about 30 minutes in front of the federal building that houses the Phoenix detention and processing facilities of U.S. Immigration and Customs Enforcement.

Six of the nine people arrested had decided beforehand to get arrested in an act of civil disobedience. The other three were arrested after police said they did not respond to orders by police to clear the street.
