Authorities say Pueblo businesses and individuals have already been hit 12 times by robbers this year, and four of the victims were banks.
The Pueblo Chieftain reported Sunday that the other victims were three convenience stores, two fast-food restaurants, a music store and two individuals.
Three men have been arrested on charges stemming from one convenience store robbery, and police say they might be linked to other robberies.
Police believe one person is behind three of the bank robberies, but no one's been arrested.
Investigators say they don't know the reasons for the rash of robberies but suspect the robbers might owe money or want drugs.
