PHOENIX - Phoenix Police and Silent Witness are now offering a reward for information that leads to the arrest of a robber who was carrying a large knife.

The robbery happened at Papa Nacho's Market, at 42nd Avenue and Thomas, on June 3, 2017.

"From the moment this guy walks into the store, he already knows what he's going to do," Sgt. Jamie Rothschild, who's with Silent Witness, told 12 News.

Surveillance video shows a man in a light gray hoodie and dark sunglasses walk into the store carrying a large knife. He waits by the door and pulls the sweatshirt up to help conceal his face.

Police say the man then threatened the woman who was working in the store. He forced her to walk behind the counter and open the register. He stole cash from inside, then ran away.

"This guy's wearing a hoodie in Arizona in June, so somebody saw him or saw him with the knife and that's the information we could use," Sgt. Rothschild said.

Police are also looking for a man caught on camera breaking into a business and stealing tools and a television.

The burglary happened at Magnum Industrial Distributors, near 42nd Avenue and Adams, on May 7, 2017.

Police say the man used a hammer to break the front door of the business. Surveillance video then captures him walking inside the business and stealing tools and a television. He was also caught on camera loading the items into a Hyundai sedan, with faded blue or gray paint, and driving away.

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