The Baltimore Police Department has activated the Maryland State Police to assist with crowds in the downtown Baltimore area, said the department on Twitter.
“Officers have observed members in the crowd setting off illegal fireworks and throwing objects near peaceful protestors and officers,” said the tweet.
Earlier tonight, the police said they were receiving assistance from the Maryland National Guard in transporting personnel and resources through the city.
The looting and destruction in New York City's Manhattan was "anarchy on the streets," said CNN Senior Media Correspondent Brian Stelter tonight.
In Midtown Manhattan, there was widespread looting along the eastern portion of the neighborhood -- along the high-end shopping district Fifth Avenue and Madison Avenue, close to Trump Tower.
"I witnessed an eyeglass shop being looted. In some cases, just windows being smashed. And other cases stores are being broken into. This has been going on for at least two hours," he said. "Between 9 and 11 p.m., it was a real sense of anarchy on the streets in Midtown Manhattan."
The looting also extended further south into Herald Square and the iconic Macy's building, which was broken into, he said. There were also fires set and buildings vandalized.
"Property damage is nowhere near as important as physical loss of life ... (but) I want you to know the property damage is widespread," he said.
Aerial videos of Midtown show looters running down streets in groups, playing a "cat and mouse game" with police, Stelter said.
Across the East River, there are still up to a thousand protesters peacefully marching in Brooklyn, despite the citywide curfew now being in place.
When asked whether they will go home, protesters told CNN reporters they need to get their message across against police brutality -- and that tonight, they are waiting to see how police engage before deciding how to respond.

Atlanta police have made 350 arrests related to the George Floyd protests since Friday, the department said on Monday.
They made 77 arrests on Friday, 157 on Saturday, 64 on Sunday and 52 so far on Monday.
Skirmishes after curfew: On Monday night, police and protesters clashed after the curfew came into effect at 9 p.m. ET, with protesters hurling projectiles and police responding by firing tear gas.
After the skirmish, the National Guard and Atlanta police got into formation and swept through the city's downtown, clearing out protesters quickly.
In Dallas, Texas, protesters who shut down a city bridge are being detained by police, hours after a curfew went into effect.
Protesters had begun demonstrating peacefully at the steps of the county courthouse earlier in the day, before marching through downtown Dallas.
The curfew, effective as of 7 p.m. local time, is only being enacted in some parts of Dallas, creating "curfew zones" -- so protesters marched around the edge of those zones, said CNN Correspondent Ed Lavandera on the scene.
When they reached the Margaret Hunt Hill Bridge, just west of downtown, they were met with hundreds of law enforcement officers.
A confrontation erupted, with the protesters and police facing off in the middle of the bridge. Police fired tear gas, and detained many protesters with zip ties. Protesters can now be seen sitting on the ground, as police continue processing those on the bridge.
"We don't know the exact reason ... for why they're being detained, but I presume it's going to be related to marching on the public streets here and essentially blocking traffic on to the Margaret Hunt-Hill bridge," said Lavandera.

New York City Mayor Bill de Blasio extended the city’s curfew through Tuesday evening, after instances of violence and property destruction in Manhattan tonight.
The Tuesday night curfew will begin at 8 p.m. ET, de Blasio said on Twitter. The curfew tonight is about to go into effect, at 11 p.m. ET.
“These protests have power and meaning. But as the night wears on we are seeing groups use them to incite violence and destroy property. Our first priority is keeping people safe, so I’m extending the curfew to Tuesday. It will begin at 8pm,” de Blasio said.
Minnesota Attorney General Keith Ellison, who is taking over the prosecution in George Floyd’s death, says they are taking another look at the actions of the other police officers present during it.
“I can assure you we are taking a fresh look,” he told CNN’s Chris Cuomo. “We plan to hold everyone accountable who is legally culpable."
He explained that while he has spent the last 24 hours reviewing evidence, he cannot ethically comment as a prosecutor.
This comes amid calls for justice in Floyd’s killing, including the legal fate of those three other officers at the scene who were fired for not saying or doing anything to stop ex-Minneapolis police officer Derek Chauvin as he kneeled on Floyd’s neck for nearly nine minutes.
“We are looking very carefully at holding everybody accountable who failed to do their duty and fell below the legal requirements of their position, or did something affirmatively that would be in violation of the law,” Ellison said.
“When we are ready, and that won't be long from now, we plan on taking the proper and deliberate action."

Former Secretary of State and 2016 presidential candidate Hillary Clinton lambasted President Donald Trump's use of force to clear protesters in Washington, DC, before taking a photo at St. John's Episcopal Church.
"Tonight the President of the United States used the American military to shoot peaceful protestors with rubber bullets & tear gas them. For a photo op. This is a horrifying use of presidential power against our own citizens, & has no place anywhere, let alone in America," she tweeted, urging Americans to vote in the upcoming 2020 presidential election.
What happened today: Just a few hours ago, Trump delivered remarks in the White House Rose Garden, before walking to the church to take a photo with a Bible.
Before his remarks, police released tear gas and fired rubber bullets at protesters near the White House in an effort to disperse the crowd for the visit to the church.
In Washington D.C., curfew has already come into effect -- but crowds of protesters are still on the streets, as well as law enforcement officers trying to clear them out.
Just a few hours ago, the national capital had been the site of chaos, with police firing tear gas and rubber bullets to drive protesters out of Lafayette Park, just blocks from the White House.
The bangs were clearly heard in the White House's Rose Garden, as President Donald Trump gave a press conference proclaiming himself the president of law and order.
Now as night falls, most of the protesters appear to be peacefully marching -- but tensions are still high, with one group throwing rocks and smashing store windows.
Mayor condemns federal police actions: Muriel Bowser, the mayor of Washington, DC, said on Twitter that the actions of the federal police at the White House against peaceful protesters had been "shameful" and "without provocation."
Watch:
New York City is less than an hour away from its 11 p.m. curfew -- but there are still thousands of protesters in Brooklyn, marching through the Crown Heights neighborhood.
The stakes feel higher tonight; there are double the amount of police out on the New York streets than the previous night, and authorities have made clear that nonessential people out on the streets will face arrest and be charged with a misdemeanor. But the protesters aren't dissuaded.
"They made it very clear they're going to keep having their message heard," said CNN Correspondent Jason Carroll, reporting from the scene. "The people I've spoken to out here say, 'Look, we are prepared to go to jail. We are prepared to do whatever we have to do to get our message out.'"
