FBI agents are trying to determine who stole 19 pieces of high-priced art, including an Andy Warhol silkscreen, from a Detroit business.
The art - worth millions of dollars, according to CNN affiliate WDIV - was taken between April 27 and April 29 from a business owned by an art collector in Detroitâ€™s Corktown neighborhood, the FBI said Tuesday. The agency didn't name the business or the owner.
The collection includes a 1960s silkscreen that Warhol used to make â€śFlowersâ€ť prints, according to the FBI. Â The other pieces of art, including paintings and drawings, were done by Larry Rivers, Francesco Clemente, Philip Taaffe, Joseph Beuys and Peter Schuyff.
Investigators suspect that the thief or thieves â€śmay have already crossed state lines, if not left the country, in an effort to sell them,â€ťÂ Â FBI spokesman Simon Shaykhet said.
â€śWeâ€™re putting a message out to art dealers, pawn shop owners, and anyone dealing in art to be aware of it,â€ť Shaykhet said.
The art was neither locked up nor on display, the FBI said.
A $5,000 reward is being offered for the piecesâ€™ recovery. They have been entered into the FBIâ€™s national stolen art database.
Up to $6 billion worth of art is stolen each year, according to the FBI.
