He had posted on Instagram just a few hours before the police statement was made.
In September, the hip hop star was charged with assault after allegedly attacking two strangers with a hatchet in Los Angeles.
He was alleged to have walked into a stranger's unlocked home and attacked two people before one of them disarmed him, according to the Los Angeles County District Attorney's Office.
