BRASILIA, Brazil (AP) -- An armed man in Brazil has heisted an 18-carat gold-plated vibrator selling for $4,000 at a luxury sex shop.

Police say he walked into the Erotica Luxo store in Brasilia, tied up a clerk and took the item from its display case. He stole nothing else.

It's high season for erotic shops in Brazil as the nation celebrates its own Valentine's Day in less than two weeks.

Store owner Vanessa Baldini tells the G1 news website the robber might get no satisfaction from Wednesday's theft. She says the Swedish-made vibrator has a stainless steel core, making removing any gold plating extremely difficult.

And she notes the robber didn't take the vibrator's charger.

She says: "I really don't know what he'll do. I'll leave it up to his imagination."
