Daniel has committed a robbery.

Explanation:

An armed robbery is a crime in which the criminal strips the victim of his property through violence, using a firearm or sharp weapon as an element of threat or directly acting with it on the victim, injuring him (or even killing him) to get the items he wants to steal.

Armed robbery is a crime against property, which differs from simple theft because in this case violence is exercised directly on the victim, while in theft violence is exerted directly to the stolen object (for example, the window of a car is broken to steal the elements that are inside), or violence is not exercised at all (for example, pickpockets).
