One person was killed Thursday during a memorial procession for Nipsey Hussle after a shooter opened fire on mourners paying tribute to the slain rapper and activist.

News reports Friday said one person was killed and three more were injured after suspects in a grey Honda opened fire on the crowd. The identities of the person who died and those wounded in the attack were not immediately released.

Police have not yet publicly identified a suspect in the investigation. The shooting comes just weeks after Hussle, 33, was shot and killed outside of his store in Los Angeles last month.

"We must stop this senseless violence," Los Angeles Police Department Chief Michael Moore said in a statement, according to the BBC.

The rapper's funeral was attended by many prominent figures in the entertainment industry, including artists Jay-Z and Beyonce, and former President Obama released a statement that was read aloud at the service.

“I’d never met Nipsey Hussle, but I’d heard some of his music through my daughters, and after his passing, I had the chance to learn more about his transformation and his community work,” Obama wrote in the letter.

“While most folks look at the Crenshaw neighborhood where he grew up and see only gangs, bullets, and despair, Nipsey saw potential,” he continued. “He saw hope. He saw a community that, even through its flaws, taught him to always keep going.”

A man named Eric Holder was arrested in connection with the rapper's shooting last month. Holder, 29, is accused of wounding two other men in the attack.
