42 Dugg Arrested After Ducking 6-Month Prison Sentence

42 Dugg's patented "Free Dem Boyz" slogan now applies to himself as well. The Detroit rapper -- who's signed with Lil Baby and Yo Gotti -- was reportedly arrested the moment he got off a plane from Memphis.

Dugg, whose government name is Dion Hayes, failed to turn himself in to a West Virginia federal prison camp last month to serve a 6-month sentence for illegal firearm possession ... according to The Detroit News.

The 27-year-old rising star, who was just named to XXL's 2021 Freshman list, hasn't exactly been living like a man on the run. In April, he released his joint album "Last Ones Left" with Collective Music Group labelmate EST Gee, and has been shooting plenty of music videos for it.

Like Pooh Shiesty -- who just got a 63-month sentence -- such legal drama could disrupt what was shaping up to be a promising rap career.
