19 injured in stampede when gun brandished at vigil for slain rapper Nipsey Hussle in Los Angeles: Police chief

Chaos erupted outside of the late rapper's store near LA's Crenshaw District.

Multiple people were injured in a massive stampede during a memorial in Los Angeles for slain rapper Nipsey Hussle on Monday, as hundreds were paying their respects near the scene where he was fatally shot.

Chaos erupted outside of the late rapper's The Marathon clothing store near the Crenshaw District on Monday night when a man brandished a gun and another person in the crowd tried to disarm him, Los Angeles Police Chief Michel Moore said at a news conference on Tuesday.

He said the incident sparked panic when a large crowd of mourners mistook the sound of breaking glass for gunfire and rushed to flee the scene.

Moore said one person was stabbed in the incident.

No gunshots were fired, he said.

At least 19 people were transported to local hospitals with various trample-related injuries, and several others were treated on the scene for minor injuries, the Los Angeles Fire Department said. Two victims were suffering from "critical" injuries, and two others had injuries described as "serious," officials said.

Officers with the Los Angeles Police Department said the crowd reacted to what was interpreted as gunfire, but no shots were fired.

"Our men and women are on scene and making every effort to protect everyone in attendance at the Nipsey Hussle vigil," the LAPD said in a statement. "Reports of shots fired at the vigil do not appear to be accurate. We do have injured in the chaos and are attempting to restore order."

LAPD officers began forming skirmish lines to keep people away from the scene. They told people to avoid the area while city workers cleaned up the scene.

"We understand the community is mourning and we feel your loss," the statement said. "We are asking for everyone to follow the officers directions and disperse from the immediate area."

Hussle, born Ermias Asghedom, was shot multiple times in the head and torso while standing outside of his store around 3:20 p.m. local time on Sunday, authorities said.

Police named 29-year-old Eric Holder as a suspect in the shooting late Monday night and asked for the public's help in locating him.

The Los Angeles Police Department did not say whether Holder had any known ties to Hussle, but law enforcement sources previously told ABC News the shooting appeared to have been targeted and personal based on how it was carried out.

The rapper, known for his philanthropic efforts and business ventures throughout south LA, received an outpouring of love and praise from some of the music industry's biggest stars in the wake of his death.

Hussle, a Los Angeles native, is survived by his two children and his longtime girlfriend, actress Lauren London.
