A police officer searches residents in a alley of the Alemao slum complex as part of a security reinforcement by the UPP (Police Pacification Unit) in Rio de Janeiro, Brazil, Tuesday, April 7, 2015. Authorities have reinforced the area due to the violence that has wracked the Complexo Alemao in recent days, with a young boy and a 41-year-old housewife killed by stray bullets as gangs and police exchange intense gunfire.
