Chad Muska Drops N Word In Felony Vandalism Arrest

Muska was first detained by security at the Roosevelt Hotel around 2AM. Law enforcement sources tell us Muska was seen spray painting his name on a nearby Coffee Bean.

While security guards waited for LAPD officers to arrive -- Muska demanded the guards let him go, and called them "ni**as" several times ... including one instance in which he said, "Fu** all these ni**as right here."

LAPD eventually showed up and arrested and booked Muska for felony vandalism -- and our sources say Muska had tagging materials on him when he was arrested.
