Beware of pickpockets as they tend to operate in tourist areas, keep your belongings secure at all times and be careful if strangers try to make conversation or distract you as it could be an attempt to steal your valuables.
Muggings and stabbings, although not a regular occurrence, have been reported. If traveling around a night, try to do so in a group.
Some businesses can be regular targets for thieves which had led to the closure of a few who can’t afford to keep repairing the damage. If possible, keep your valuables in a safe and secure place, such as a safe in your accommodation.
There can be a lot of drunk people around at night, so try not to be on your own and be aware of who is around you.
