A shootout last month, the first gun battle in seven years between Rio de Janeiro police and drug traffickers in Santa Marta, has raised concerns a police campaign - for which Santa Marta, with its reputation as a peaceful slum with stunning views, was the model - is running out of steam a year before half a million visitors arrive for the 2016 Olympics. No one was injured in the maze of alleys and steps of the "favela" that is home to 6,000 people, but the incident, in the wake of the stabbing deaths of a cyclist and a German tourist, has sparked fears that after years of progress, violence is on the rise again in Brazil's postcard city.
