Please be aware that groups of thief are still VERY active in Arica. Our daypack was stolen doing the old distraction trick. Due to the fact that we had our passports in the daypack (just got of the bus) we had to abort our plans and fly to Santiago for emergency passports. At the the 3 different embassies we had to go to, all three showed us piles of records of similar incidents from Arica.
Yes, it was our fault to be careless, but having travelled in Chile many times we were lulled into false security and at 05:30 in the morning at the bus terminal, we felt victims to the oldest trick in the book. Apparently, the authorities do not want to publicise the fact or event combat it that Arica is at par with Vina del Mar in regards to organised thief but.
