Young currently lives right near Brown's valley home in Tarzana, CA -- which was surrounded by the SWAT team and police helicopters Tuesday morning after Brown allegedly threatened a woman with a gun.
"Chris Brown, you gotta move," Young says with choppers still flying overhead ... "Go on, get away from here!"
Young says Brown is essentially "making the block hot" -- attracting way too much police attention and he's worried the trouble is going to spill over his way.
"There's really only two of us [black people] over here ... at this rate you gonna make it one."
"Please, I like you, man. You my dawg. We go out, but you go out away from over here ... go!"
