Grammy-nominated rapper and community activist Nipsey Hussle has been shot dead outside his Los Angeles clothing store, aged 33.

Three men were shot on Sunday outside Marathon Clothing, and one of them was later declared dead in the hospital, Police said without disclosing the identity of the victim.

The LA Times and NBC quoted police sources as saying the victim was Hussle.

The city’s mayor, Eric Garcetti tweeted:

“Our hearts are with the loved ones of Nipsey Hussle and everyone touched by this awful tragedy. LA is hurt deeply each time a young life is lost to senseless gun violence. My Crisis Response Team is assisting the families coping with shock and grief.”

Police said the other two men were in a stable condition. The gunman fled, and no arrests have been made.

“At this point, we’re not even sure as to whether he walked up, rode a bicycle or drove up in a car,” said LA police lieutenant Chris Ramirez.

Just hours before his death, Hussle tweeted: “Having strong enemies is a blessing.”
