CHICAGO >> Chicago police say three people stole a rare, diamond-encrusted clock worth more than $400,000 from an antique show at the city’s Merchandise Mart.

Authorities say two women and a man approached a booth at the show on Sunday afternoon. The man and one woman distracted employees while the other woman took the clock.

Lori Paige is chief marketing officer for New Orleans-based M.S. Rau Antiques, which was displaying the clock.

She says the Asprey & Co. clock is valued at $425,000.

Paige says surveillance video from the booth was given to police and she’s hopeful the clock will be found.
