Travis Porter aren't known for making gangsta music, but that reputation just might change. MTV News has confirmed that group member Strap was arrested at Hartsfield-Jackson Atlanta International Airport on Wednesday morning (February 15) for trying to clear security with a firearm.

A Hartsfield-Jackson official indentified the arrested individual as Harold Duncan (Strap's birth name) and confirmed that he was arrested at the airport and has since been transferred to Clayton County jail in Jonesboro, Georgia.

The trio -- Ali, Quez and Strap -- have been a staple on the Atlanta rap scene for a number of years. They first gained notoriety after appearing on Roscoe Dash's 2008 hit "All the Way Turnt Up," and in 2010, the guys broke through off the strength of their strip-club anthem "Make It Rain." The song peaked at #9 on the Billboard Rap charts and piqued interest for the group's oft-delayed debut album on RCA Records.

The group finished in the top five on MTV News' 2010 "Hottest Breakthrough MC" fan poll. (The award eventually [article id="1679306"]went to Wiz Khalifa[/article].) Battling album delays, Travis Porter continue to release singles. Their 2011 track "Bring it Back" features Oakland rap legend Too $hort and appears on the group's mixtape Music, Money, Magnums. TP's latest single, "Ayy Ladies," features Young Money's Tyga. Earlier today, Travis Porter dropped a preview clip for the video on YouTube, and the behind-the-scenes video features Chris Brown and Meek Mill.
