Beverly Hills police are investigating Kanye West after allegedly assaulting a young man at a Beverly Hills office building.

According to TMZ's report this past Monday, the 36-year-old rapper punched an 18-year-old man who was reportedly screaming racial slurs at his fiancée Kim Kardashian. West's bride-to-be was en route to a meeting in Beverly Hills at the time of the incident.

Kadashian was going to a meeting for her new home when a young man began yelling at paparazzi gathered outside, dropping the n-word. The report said that Kim scolded him for his language and he turned on her, saying, "I will kill you, ****!"

The rapper known for his fiery temper confronted the teen after calling Kardashian on the phone, a source told E! News. "Kanye called her phone and she answered and the man continued yelling at her," the source continued. "Kanye overheard and came running down...he confronted the guy."

A second source added that the rapper called Kardashian trying to find her because she was late to the appointment, and when she answered, he could hear her "crying hysterically."

ABCNews reported that according to a source close to Kardashian, a man called the reality TV star a "n----- lover" and hurled obscenities at her leaving the reality star "shaken."

A rep for the Beverly Hills PD confirmed LAPD arrived at the scene after the couple had left, and has begun an investigation. According to the Beverly Hills Police Department, West, is a suspect in a misdemeanor battery that also occurred in Beverly Hills.

West already faces charges of battery and attempted grand theft in an altercation with a photographer at Los Angeles International Airport last summer. West pleaded not guilty to the charges in connection with the incident.

During West's last tour date of 2013 on the Yeezy tour, the rapper told the audience that he had resolved to "stop talking" smack in 2014. "This is the last time you'll ever hear me say [anything] negative about anyone," he told the Toronto audience.
