Two weeks of tension over the death of 25-year-old Freddie Gray boiled over on Monday night as rioters clashed with officers and National Guardsmen in the city's streets in the worst violence to date. The chaotic scenes included hordes of officers fleeing from a barrage of rocks and bottles tossed by protesters, as well as looting and cars and businesses set on fire, resulting in hundreds of arrests.

The heightened violence came just hours after Gray's funeral on Monday (April 27), with many Baltimore residents frustrated that the investigation into how Gray suffered a fatal spinal injury while in Baltimore Police custody appears to be moving too slowly.

How did it all begin? Here's a timeline of the Gray case:

Gray was arrested on April 12 after police said he 'fled unprovoked' from officers.

Baltimore residents pray for Gray while he's in the hospital.

The protests begin.

As Gray lies in a Baltimore hospital in a coma, residents begin to gather on the streets on April 18, with crowds growing each day after Gray is pronounced dead on April 19.

The crowds swell.

State Troopers sent in, arrests begin.

Gray's family makes a plea for for peace as protest violence spreads and Gray is laid to rest.

Hours after a wake for Gray on Sunday, protesters filled the streets again, with the situation getting critical on Monday, when the Governor called in the National Guard and a 10 p.m.-5 a.m. curfew was put in place.

Following Monday's funeral, protesters engaged police, throwing rocks and bricks, some of which were thrown back by officers as daytime looting broke out.

The night of violence ended with at least 15 police officers injured, 200 arrests, 144 vehicles set on fire and 15 building fires. Gray's mother, Gloria Darden, said the family wants justice, but not in the streets. "I want y'all to get justice for my son," she said. "But don't do it like this here."
