RIO DE JANEIRO -- Tensions are rising in a Rio de Janeiro slum following the death of an elderly woman hit by a stray bullet during a gunbattle between police and alleged gang members.
Three cars were burned Monday in the Alemao complex of slums near a police outpost. Officers are investigating to see if it is related to the death of the woman Sunday.
It's the latest unrest to hit Rio's slums just weeks before the country hosts the World Cup.
Tensions have been rising in recent months amid an ambitious security push that sees officers invade slums long held by drug gangs then create permanent police posts.
