Cops came down on rapper Nipsey Hussle in a big way Tuesday night in the middle of a Trayvon Martin protest rally … handcuffing him after suspecting he was brandishing a gun.
Law enforcement sources tell us … LAPD cops saw Nipsey doing something that made them believe he was walking around with a firearm. They descended on the rapper and cuffed him, but quickly determined he did NOT have a gun and they let him go.
It’s unclear if Hussle was part of the rally, which took place in Leimert Park — the scene of violence the night before.
