Big bank take lil bank…

YG is facing felony robbery charges for allegedly snatching a man’s chain off of his neck in Las Vegas back in May.

Via TMZ:

Vegas police tell us … the incident went down in late May at the Cosmopolitan around 4 AM, after a man approached YG and asked for a pic but was turned away by his crew. We’re told the guy told YG he’s not a real celeb … and casino’s surveillance footage shows YG retaliating by yanking a chain off his neck.

We’re told the chain fell to the ground, and YG is then seen on video picking up the necklace pendant — valued somewhere between $3,000 and $9,000 — before taking off.

An arrest warrant was issued for YG who turned himself in on Thursday.

He was later released after posting $20,000 bail.

The alleged victim is suing the rapper for $250,000 claiming he ordered his goons to mollywop him before he took his chain.
