In the video, the men were wearing bandanas to cover their faces and walked toward a jewelry display case. One of the men smashed it open with a hammer and another one grabbed the jewelry.
The robbery happened at an independently owned jewelry store inside a Superior Grocers on Main Street shortly after 2 p.m. on Father's Day.
"It's a brazen act. I mean at 2 o'clock in the afternoon walking into a busy business with the masks on, crowbars and hammers in hand," Cpl. Anthony Bertagna said.
The suspects stole expensive wedding bands. The owner values them at about $4,000. But authorities said the owner's response may have prevented the men from taking more.
His frightened customers ran away and he grabbed a baseball bat. He waved it and then threw it at the robbers as they ran out.
One witness followed the men and said they were driving a purple Prius.
Anyone with more information is urged to call the Santa Ana Police Department.
