(CNN) -- A Green Party candidate in the California's governor's race was arrested Tuesday after trying to get into a debate she was not allowed to participate in.

Laura Wells, 62, from Oakland tried to enter a debate between leading candidates in the race: Republican gubernatorial nominee Meg Whitman and Democratic opponent Jerry Brown, police said.

The event was at Dominican University of California in the northern city of San Rafael.

Wells was not allowed to be part of the debate because of her lack of support in the polls, CNN-affiliate KTVU reported.

"When the independent parties are not at the table, California is not at the table," Wells told the affiliate before she was led away by security officers.

Wells was dressed in a bright green dress and was backed by a contingent of supporters who were holding protest signs.

San Rafael police said Wells was arrested for trespassing after trying to use a bogus ticket to get into the event and then arguing with school security officers.
