Lil Wayne Held Up by them FED Boyz!

Lil Wayne got away scot-free after being stopped and searched by federal agents as soon as he got off the plane in Miami's Opa-Loca Airport earlier this week.

DEA agents performed a search on Weezy -- who is still on felony probation from incidents involving guns. Fortunately for him, the "Lollipop" rapper came up squeaky clean and was let go.
