Migos and Chief Keef's GBE crew have exchanged words from time to time over the last year, and it looks like things got physical on Sunday night.

The Atlanta trio were performing at Stadium in Washington D.C. when, according to eyewitnesses on social media, Quavo's chain was taken. Keef then posted a picture of the chain on his Instagram account, with the caption, "What's this?" according to XXL, but the photo has since been deleted.

The issues between the two camps started late last year, Keef fired a shot at the "Fight Night" rappers on Twitter after a perceived slight on the track "Brockanese."

"You know, people gonna take it however they gonna take it and put it however they wanna put it,” Takeoff told MTV News in December about the crew's track "Jealousy," which many believed was a response. “If you listen to the song, it’s self-explanatory. If [I'mma] do one, [I'mma] say ya name to keep it 100. Ain’t no need for me to be sneak-dissin’.”

Then, earlier this month, Migos had a run-in with GBE's Capo. Takeoff posted a quick snippet of an apparent altercation on Instagram, along with the caption, "Caught @elcappgguod slipping lastnight in his city."

Capo addressed the incident on Twitter. "Migos Soft as hell Y'all Jus Had 20 n---as And I was by myself F--k n---as!" he wrote. "On blood grave They all Swung and I didn't Get hit 2times they Lil rappin Ass had 20 n---as Wit Em And ain't even do sh-- But woof!"

Fredo Santana, also part of GBE, fired back at Migos shortly after.

Migos have yet to speak out about to the alleged incident over the weekend.
