Investigators say the first armed robbery took place early Saturday morning and in the next 24 hours the suspects would rob three other stores at gunpoint.
Police are hoping some surveillance photos will help lead to an arrest.
This is just one 7-11 store where Fresno police say two gunmen demanded money. The robbery happened at about midnight on Saturday in the area of Blackstone and Minarets and only took a few seconds.
Action News got a better look from surveillance footage of the two suspects who investigators say robbed four stores at gunpoint just this weekend. Kamal Singh of Valero said.
Singh is anxious after the Valero station his family owns was hit. He says the two men took less than a minute to steal cash and then take off.
"I am hoping they catch them. You can't be running around and doing that to everybody. It's hard earned money," Singh said.
The crooks also stole from a Fastrip store near Clinton and Maroa at about 4 a.m. Sunday.
Detectives believe a man who wearing a dark hoodie walked into to those stores with a gun backed up by his partner in this grey sweatshirt. People who live nearby say they're banking on these pictures to help catch the criminals.
"I just fear maybe I come over here with my kids or my wife and something like that happens. It just scares me," Rene Lobera of Fresno said.
There is a thousand dollar reward to anyone who comes forward with information on these crimes. Anyone with that information is asked to call Fresno Police in Downtown Fresno.
