TAYLOR (WWJ) – Two small metro Detroit electronics stores were raided Tuesday by Homeland Security agents.

One of the ACE Wholesale, Inc. storefronts is located on Telegraph Road in Taylor, where it shares a duplex with a Mattress World, managed by Jim Zupke.

“It’s an electronics wholesale business. They buy and sell electronics and, apparently … well, apparently, I just don’t know,” Zupke told WWJ Newsradio 950’s Mike Campbell. “This is unusual. They’ve been quiet neighbors … they do their business, we do our business … nothing unusual.”

While a man in a landscape truck put plywood over the broken-out front window on the store, Homeland Security agents and dogs worked the back of the store — including a “dock” area where a rented box-truck sat half-loaded or emptied.

A separate team of Homeland Security agents and local police, meantime, raided a second ACE Wholesale store on Big Beaver near Livernois in Troy.
