Rob Kardashian is being investigated by Los Angeles Police Department (LAPD) for allegedly threatening a man over her fiancee Black Chyna.
The LAPD's media coordinator, Tony, has confirmed the news of investigation to Entertainment Tonight.
"Last night North Hollywood took a crime report naming Rob Kardashian as a suspect in a criminal threats report. Threat Management is aware and is looking into the incident," he said.
Tony has not disclosed the identity of the alleged victim but according to sources, the 29-year-old reality TV personality is believed to have physically threatened actor-singer Pilot Jones, a friend of Chyna, who is currently pregnant with Rob's first child.

A reported text message from Rob to Jones reads, "Leave my wife alone. I'm not playing with you."
Also, according to Law enforcement inside information, there are other texts in which Rob generally threatens Pilot with physical harm, which is "a little murky and general.
