Roads and streets in the city emptied quickly on Wednesday night in Baltimore, as a citywide curfew went into effect.

Hundreds of police rolled into town in armored vehicles wearing full riot gear before the curfew began.

The second night of curfew comes following riots over the death of Freddie Gray in police custody. Police are expected to finish the investigation into Grays death on Friday.

In the meantime, a sense of calm has returned to the city, with local schools and businesses re-opening. In the wake of the violence in Baltimore, President Barack Obama has called for reflection on poverty and social problems in the country.
