RACINE, Wis. (CBS 58) -- A demonstration in Racine this afternoon put a spotlight on some recent arrests by immigration officials.

"One voice could make an impact but it's easier for more than one to make a bigger impact," said Oscar Luis.

Luis was one of the demonstrators, marching through Racine on Wednesday.

They're angry about the arrests of four men including Ricardo Fierro since late July.

Fierro is the former local director of the Hispanic Chamber of Commerce.

He was arrested at his home.
