I have obtained NEW VIDEO of the Chris Brown valet incident ... in which it's clear -- BROWN THREATENED THE VALET.
The new footage shows Chris cussing at the valet in front of PINZ bowling alley in Studio City, CA -- where Brown had just attended a charity event for inner city youth.
The valet had asked for the $10 fee before handing Brown the keys -- but Chris refused to pay because he was only at the event for a short time and didn't feel it was fair.
Chris exploded in anger ... getting right in the valet's face and yelling, "Gimme my f*cking keys ... f*ck ten dollars."
Then comes the threat -- "Gimme my keys ... we gonna turn this whole spot up ... I promise you."
Translation -- WE'LL GET VIOLENT IF YOU DON'T HAND OVER THE KEYS.
That's when someone from Brown's camp appears to give the valet $10 ... and Brown snatches his keys back and says, "Funky ass ten dollars."
