A person commits robbery in Arizona if in the course of taking any property of another from his person or immediate presence and against his will, such person threatens or uses force against any person with intent either to coerce surrender of property or to prevent resistance to such person taking or retaining property. The definition of robbery can be found in A.R.S. 13-1902, and the crime of robbery is a class 4 felony in Arizona.
However, robbery can carry more severe punishments as well. For example, robbery is charged as aggravated robbery, a class 3 felony, if one or more accomplices are present in the course of the robbery. See A.R.S. 13-1903. Lastly, a robbery can be charged as armed robbery. A person is guilty of armed robbery if, in the course of the robbery as defined in 13-1902, the person or an accomplice
1. Is armed with a deadly weapon or a simulated deadly weapon; or
2. Uses or threatens to use a deadly weapon or dangerous instrument or a simulated deadly weapon.
Armed robbery is upgraded to a class 2 felony charge as described in 13-1904.
