The home of NBA superstar Lebron James was vandalized with a racial slur, according to multiple media reports Wednesday.

A racial slur that contained the "n-word" was spray painted on the outer gate of James' private home in Los Angeles, California, witnesses said.

The paint was later sprayed over, according to Los Angeles Police Department (LAPD) officers who responded to the scene around 6:45 a.m. local time (1345GMT).

"LAPD is investigating a vandalism at the residence of NBA player LeBron James in which a racial slur was spray painted on a private fence," the department said in a statement via Twitter.

James' team, the Cleveland Cavaliers, did not respond to Anadolu Agency's request for comment.

The motive for vandalism against the three-time NBA champion's home is not yet known.

The four-time league MVP has been outspoken against social injustice.

At the time of the incident, James is believed to be in Oakland, California, as his team prepares for Game 1 of NBA Finals against Golden State Warriors scheduled for Thursday.
