Windsor police and Crime Stoppers are looking for public help to identify the suspects in a break and enter at G & G Jewelry last Wednesday.
The overnight heist at the downtown jewellery store happened around 3:40 a.m., that's when the alarm alerted police.
The suspects reportedly entered through the back of the University Avenue store, using a tool to pry open the door.
G & G Jewelry was closed fo the day after the break in, as glass display cases had been smashed inside the store and large quantities of jewellery stolen.
At the time of the theft, police said they had surveillance video from inside the store and nearbuy businesses they hoped would provide clues.
On Monday, police released an image taken from surveillance and are asking the public for help.
Anyone with information is asked to contact 258-8477 (TIPS).
This is the third time in less than four years that thieves have broken into the store.
