A pair of unidentified assailants robbed the UPS Store at 12995 N. Oracle Road in Oro Valley on Tuesday, Dec. 1.
The men entered the store at 6:15 p.m. through an unlocked back door. They demanded cash, threatening the only employee on duty with a 7-inch serrated knife, according to Oro Valley police.
The employee was unharmed.
In addition to an undetermined amount of cash and credit card receipts, the men also stole the employee's wallet and cell phone.
Both men were described as Hispanic. One was approximately 6 feet tall, 200 pounds and between the ages of 20 and 30. He was clean-shaven with a medium complexion, wore blue jeans and a black hooded sweatshirt with "Nike" on the front.
The store employee described him as "chunky."
The second man was also approximately 6 feet tall but with a thin build, weighing 160 to 170 pounds. He also was described as between 20 and 30 years old.
He wore a dark sweatshirt and dark "Dickies" style pants.
Police believe the men may have fled on foot.
The incident was the first reported holiday season armed robbery in Oro Valley since 2003, Oro Valley Police Lt. Chris Olson said.
"When we see something that we haven't seen before like an armed robbery during the holiday season, we start to have concerns," Olson said.
He said the poor economy over the past year could be a motivating factor for criminals like those who robbed the UPS Store.
"People get desperate, especially at holiday times," Olson said.
Police ask that anyone with information pertaining the robbery call the Oro Valley Police Department at 229-4900 or 88-crime.
