They now believe two men may be behind the spree, which began back on Saturday, December 14, around 6 a.m., when one of them broke in to the Grand 99 Cents Store on Jamaica Avenue by cutting a hole in the roof.
The men were caught on the video cashing in lottery tickets at a store in Brooklyn.
Authorities say they broke into at least seven stores while they were closed through the roof or air conditioner vent.
The men are accused of stealing money, lottery tickets and phone cards.
In the most recent robbery, the thief cut his way through the roof of a grocery store on Jamaica Avenue and 90th Street in Woodhaven. He then went shopping for everything from phone cards to toilet paper, even breaking into a lottery machine for the cash.
He made off with about $1,000 and $600 worth of phone cards.
Authorities say he usually does away with any evidence in the security system, but in that case, he cut the power but never erased the video. He was caught on video by at least three cameras both inside and outside the grocery.
The man or men appear to wear a protective suit with the face covered, in addition to a flashlight on the forehead.
Anyone with information is asked to call Crime Stoppers at (800) 577-TIPS (8477).
