A man who police believe fatally shot rapper Nipsey Hussle on Sunday was taken into custody by authorities in Los Angeles.

The LAPD announced the arrest of Eric Holder in a tweet, writing: “Thank you to both our community for the heightened awareness/vigilance, and our partners at @LASDHQ.” You can see the tweet below.

“Nipsey and the man suspected of killing him knew each other, and the shooting appears to be the product of a personal dispute, Los Angeles police Chief Michel Moore told reporters Tuesday morning,” CNN reports. “Moore declined to elaborate on the feud between the two, saying he didn’t want to jeopardize any potential prosecution, but he said the suspect — who was identified via surveillance video and witnesses as Holder — approached Nipsey and others multiple times, engaging them in conversation.

“At one point, Holder, 29, returned with a handgun and ‘purposely and repeatedly fired’ at the men, injuring two of them and killing the rapper, he said.”

CNN adds: “Though the rapper was a member of an arm of the Crips street gang and police believe Holder belongs to a gang as well, Moore declined to specify any gang affiliation and said the dispute between the two does not appear gang-related.”
