Yesterday during a Travon Martin protest rally at Leimert Park in Los Angeles, authorities detained rapper Nipsey Hussle for suspected possession of a firearm. Law enforcement sources tell TMZ that the LAPD saw Nipsey doing something that made them believe he was walking around with a firearm. Nipsey was handcuffed for a short while and was later released when it was realized that there were no weapons on his person.

Nipsy tells TMZ … he’s especially upset at the way cops treated his brother (who is disabled) — “They pushed his face on the concrete. They dropped a knee in his spine then twisted his arm and cuffed him while he was not resisting.

“Nipsey says cops held them on scene for 4 HOURS … before they eventually determined no one in Nipsy’s crew had a gun.

Despite being at the Trayvon Martin rally … Hussle doesn’t think the situation was a case of racial profiling — “I think it was the result of hyper sensitive LAPD officers overreacting once again.”
