Police have released security video of two suspects in a brazen daylight smash-and-grab at a Brooklyn jewelry store in which they got away with about $250,000 worth of jewelry. Police say they’re also looking to question a woman seen in the video browsing the display cases in the store and then holding open a locked door to let the suspects in. The masked men walked into the store at 1064 Coney Island Ave. in Midwood the afternoon of Wednesday, Dec. 3, and one of them showed a gun while the other used a hammer to break a glass display case and grab merchandise.
