Police are racing to find the known gang member wanted in connection with Nipsey Hussle's murder who is now feared to be the subject of a gang hit.

Late on Monday, police named 29-year-old Eric Holder, a known member of the Rollin' 60s gang, as the suspect in Hussle's murder.

Police sources say he and the rapper were known to one another and that it was a gang-related killing but they have not revealed further details or suggested a motive but they say it was 'personal' and had not been ordered by gang leaders.

He is on the run and police on Tuesday urged him to hand himself in to authorities.

He is accused of approaching Hussle in the parking lot outside his store and arguing with him and two other men then walking away and returning with a handgun.

He opened fire, shooting all three of them, then fled in a waiting car that was being driven by an unidentified woman.

The brutal killing was caught on surveillance camera footage.

Now, it is being claimed online that he has been 'green lit' by the Crips, the gang to which he belonged and allegedly 'snitched' on, to be killed.

There is now a race between the LAPD and the gang's members to find him. Hussle was a hero in southern L.A. where he was trying to legitimize gang members by developing the area and eradicating violence.

He was a former Rollin' 60s member but was eager to work with the LAPD to stamp out gang wars peacefully and maintained strong relationships with the community.

LAPD Chief Michael Moore urged him to turn himself in to the authorities on Tuesday.

'To Mr. Holder, who I am confident is watching this and listening to these media accounts, I ask him to surrender.

'Find a local law enforcement agency, go to a station and surrender. Stop this. Stop this from continuing,' he said.

He added that he posed a 'substantial risk' to the public.

On Monday night, chaos broke out outside Marathon Clothing, the store which he owned and where he was killed, as hundreds of people who had gathered to pay their respects started running from the scene without explanation.

The stampede injured 19 people but it remains unclear what sparked the panic.

The LAPD commissioner Steve Soboroff said he was 'very sad' about the news when it emerged on Monday.

On Tuesday, he and others gave a heartfelt tribute to the rapper as they pleaded for his killer to hand himself in.

Soboroff fought back tears as he read aloud an email that Hussle sent him on February 26 about working together.

'We want to hear about your new programs and your goals for the department as well as how we can help stop gang violence and help you help kids.'

He was writing on behalf of himself and Roc Nation and the meeting was due to happen on Monday, the day after he died.

While it is not thought to be related to his killing, police say it is symptomatic of the city's gang violence problem.

Commissioner Soboroff said he had even picked out his clothes for the meeting because he was so excited for it.

'I was ready for the meeting, I was excited about the meeting. Here was somebody coming in to say, "How can we help? How can we be a partner?"

'On Sunday morning, I took out my clothes for Monday. I was going to wear a save th children tie. It was all ready to go,' he said.

Commissioner Soboroff wore the tie to Tuesday's press conference instead. City

Councilman Marqueece Harris-Dawson described Hussle as an 'extremely bright light' and a 'son and grandson' of the neighborhood.

'[He was] a shining example of the best of what we can be, the best of what it means to seek an carry out a redemptive charge,' he said.

Surveillance video captured the moment the rapper was killed.

The video captured a man, now allegedly believed to be Holder, approaching Hussle and a group of men as they stood by a white car parked at the front of his store.

Seconds later, Hussle could be seen dropping to the ground while multiple men fled the scene as the gunfire rang out.

The gunman could be seen firing from a distance before approaching and shooting multiple times at close range.

He then appeared to kick Hussle before fleeing the same way he came.

Sources told the Los Angeles Times that Holder had gotten into a dispute with the rapper in the lead up to the shooting.

Prior to Holder's name being released, sources said detectives believed the gunman was someone the Hussle knew and that he had gang ties. The sources added that shooting was likely personal and not part of a larger gang feud.
