PHOENIX - Phoenix Police and Silent Witness are offering a reward of up to $1,000 to find four criminals who were caught on camera.

In one crime, two men broke through the wall of the Cricket Wireless store near Dunlap and I-17 on Saturday, September 26, 2017. The surveillance video is extremely clear and shows the men breaking through the wall, entering the store and stealing bags full of cellphone cases and other times.

"Anytime somebody is taking items in large quantity, they're usually doing it for resale," said Sgt. Jamie Rothschild, who's with Silent Witness. "And when you're talking about cellphone items, they know that everybody has a cellphone. So, they probably think they can sell them pretty easy."

In a separate crime, two men were caught on camera stealing four packs of beer from a convenience store, while acting as though they had a gun.

The robbery happened at the Circle K on Dobbins and Central Avenue on September 16, 2017.

Police say two men walked into the store, immediately grabbed four 12-packs of beer and then started to leave without paying. At one point, police say one of the men showed a handgun. That turned the crime from a theft into a robbery.

"Anytime you introduce a weapon or the threat of a weapon, you're increasing the risk of harm to anybody," Sgt. Rothschild said. "There is nothing good that can come of this."

If you recognize any of the men, you're asked to call Silent Witness at 480-WITNESS. You can remain anonymous and receive a reward of up to $1,000.
