Cape Verde: any safety alerts regarding hasslers, con men, thieves or muggers specific to this region?

I'm travelling to Cape Verde (Cabo Verde in Portuguese) & want to know what expectations I should have regarding possible hasslers, con men, thieves or muggers.

Some countries/locations in the world definitely have specific issues for travellers, for instance, a lot of hasslers in Morocco, or another example, many thieves/pick-pockets in Paris.

Is there such a thing I should pay particular attention to in Cape Verde? ie. beware of muggers in some specifics locations?

Note: before posting this question, I checked that it was "on topic" (safety topic in this case) & really focussed my concern on very specific subsets of the "safety" topic.
