Earlier in the day, thousands gathered for Freddie Gray's funeral. Gray died of an unexplained spinal injury while in police custody.

Outside the mall, a young person threw a flaming trash can at the line of officers, igniting a patch of grass nearby.

The University of Maryland campus in downtown Baltimore shut down its campus at 2 p.m., saying it has been warned by the Baltimore Police Department that "activities" in the area may turn violent.

In an alert to students and staff, the university says "the safety of our students and employees is of paramount importance. Please vacate the campus as soon as possible."

School spokesman Alex Likowski said he didn't know what type of activity might be passing through campus or what prompted the warning from police.

The university's main campus is in College Park, about 30 miles south of Baltimore.

The casket was rolled out of the church with the family following behind. Within minutes, the entire church was empty, leaving the musicians to play a rousing processional.

As people left, there was an image of Gray projected on the screens flanking the altar. It showed him wearing a striped polo shirt, baseball cap, pants and sneakers. The front of the program read, "Loving Memory, Freddie Carlos Gray Jr."

The NAACP says it's opening a satellite office in Freddie Gray's Baltimore neighbourhood, known as Sandtown.

In a statement on the organization's Facebook page, the NAACP said its police reform action in Baltimore dates back to the 1980s, and has involved targeting racial profiling cases. The NAACP said it also filed legal action involving traffic stops targeting black people and another one involving a high rate of incarceration of black people in the city.

Grey, who is black, died of an unexplained injury he suffered in police custody.

The satellite office in Gray's neighbourhood will include legal support from the national office, the NAACP said.

The Rev. Al Sharpton says he plans to meet with activists and faith leaders in Baltimore to schedule a two-day march from Baltimore to Washington in May.

He says the march will aim to bring the cases of Freddie Gray, Eric Garner, Walter Scott and Eric Harris to the attention of new Attorney General Loretta Lynch.

In a statement Monday before Gray's funeral, Sharpton says he had been resisting getting personally involved because he wanted to wait until he saw what the police department's investigation found. But now he says since the department's report may not be released publicly, he has decided to travel to Baltimore.

Police have said the department would release its report to the State's Attorney's office on Friday and send out updates when new information is available.

Baltimore police say the department believes three notoriously violent gangs are now working together to "take out" law enforcement officers.

In a statement Monday, the department called it a "credible threat" and said members of the Black Guerilla Family, the Bloods and the Crips have formed a partnership against the police.

The department warned other law enforcement agencies to "take appropriate precautions."

The police statement came as mourners gathered for the funeral of Freddie Gray, who died of a mysterious spinal injury while in police custody.

Police spokesman Capt. Eric Kowalczyk would not say whether the threat is related to the death of Gray. Kowalczyk said the threat announcement has been circulated to law enforcement agencies nationwide.

Earlier this year, Baltimore police said the Black Guerilla Family sent a man into the Northeastern District station house with marijuana, cocaine and a loaded gun to test the station's security.

The daughter of Eric Garner, who died of a chokehold in the custody of New York City police, is at the funeral of Freddie Gray.

Gray suffered critical spinal injuries while he was in Baltimore police custody.

Erica Garner, 24, says she came Monday because watching the video of Gray crying out when he was arrested reminded her of the crying and agony that her father went through.

"My father was yelling out, 'I can't breathe and (Gray) was yelling out — he didn't have any words but he was just hurt," she said.

She says she hasn't met Gray's family, but would tell them: "I feel your pain. I know what you're going through. Stay strong and continue to fight."

Garner died last July after police placed him in a chokehold on a Staten Island street.

11:45 a.m.

Grey died after suffering a critical spinal injury while he was in police custody. His death has prompted marches and rallies for the more than a week.

The church, which has a capacity of 2,500, is full of mourners.

Just before the start of the service, members of the Gray family gathered in front of the casket for a second time. Gloria Darden, Gray's mother, sat down, and someone handed her a box of tissues.

The casket is closed and a wreath of white roses is on top of it.
