Thousands of dollars’ worth of jewelry were stolen Wednesday afternoon during a smash-and-grab robbery at Trumbull Mall.

Police say three masked robbers with hammers smashed the glass display case at Kay’s Jewelers before escaping in a dark four-door sedan.

Shoppers heard the glass shattering and thought it was a gunshot.

Police later determined no weapons were involved.

Anyone with information is asked to contact the police.
