National Guard troops fanned out through Baltimore, shield-bearing police officers blocked the streets and firefighters doused still-simmering blazes early Tuesday as a growing area of the city shuddered from riots following the funeral of a black man who died in police custody.

The violence that started in West Baltimore on Monday afternoon — within a mile of where Freddie Gray was arrested and put in a police van earlier this month — had by midnight spread to East Baltimore and neighborhoods close to downtown and near the baseball stadium.

It was one of the most volatile outbreaks of violence prompted by a police-involved death since the days of protests that followed the death of Michael Brown, an unarmed black man who was fatally shot by a white police officer in Ferguson, Missouri, last summer.
