CENTURY CITY – Thirteen people were arrested today in Century City during a march and rally in support of recently laid off janitors, police said.

About 300 people attended the march and rally outside the Century Plaza office building, where the janitors used to work, said Richard French of the Los Angeles Police Department.

“Thirteen people were arrested for blocking traffic. The arrests were without incident,” French said.

Earlier, Jacob Hay of SEIU United Service Workers West, the union organizing the protest, said the rally could lead to civil disobedience, including blocking traffic on Avenue of the Stars, Century Park East and Constellation Boulevard.

“It was a peaceful protest,” Hay said. “Even the arrests were peaceful. The police did their thing, but there were no incidents.”

The protest ended around 3 p.m.

The rally was part of a four-day series of events that began this past Tuesday on behalf of 16 laid-off janitors who worked at the building, Hay said.
