Lil Xan is reportedly being investigated for assault with a deadly weapon after footage of him pulling out a gun on a Tupac fan at a gas station went viral.

LAPD's elite Robbery-Homicide Division told TMZ that they have taken over the investigation which could lead to a very serious felony. The man who filmed the incident filed a police report and the officer filed a report for assault with a deadly weapon.

Xan had once referred to Tupac's music as "boring," and he was challenged by a fan when he pulled up to get some gas

"You a b*tch. Look at this little b*tch. Do something, homie," the man filming says, mocking Xan, who walks back to his vehicle and pulls out a handgun.

Xan yells "Get out!" before the Pac fan can be heard saying, "Look at this guy pulling a gun, right now. Pull that sh*t out again, homie."
