Beware of your surroundings and travel in well lit areas to avoid being followed or assaulted.
Drug crimes are present in the city, this shouldn’t effect tourists but be aware that you may be offered drugs. Firmly say no and walk away.
Beware of pickpockets as they tend to operate in tourist areas, keep your belongings secure at all times. Be careful if strangers try to make conversation and distract you as it could be an attempt to steal your valuables.
