Migos are being sued for provoking a riot during a 2015 concert in Albany, New York, where several people were stabbed, according to TMZ. The suit also alleges that the venue lost sales, and that the concert led to long-lasting damage.

Per the lawsuit—which was filed by the venue, Albany Armory—Migos appeared at the show hours after their call time, which reportedly upset the audience. The lawsuit alleges that upon arrival, the trio smelled of weed and alcohol and declined to honor a scheduled meet-and-greet, which many fans paid for.

“The actions of the defendants caused patrons to be stabbed, robbed, beaten, severely harmed, and injured as the defendants continued to incite a select group of individuals to continue the onslaught of attacks, assaults, and destruction of the premises,” the lawsuit reads. “Despite the severity of the incident the defendants were seen laughing and egging the crowd on as metal gates were ripped from the ground and thrown into the crowd.”

The venue owner, Albany Basketball & Sports Corporation alleges that it lost its liquor license “as a result of the fight and subsequent negative media attention,” requiring the venue to call off concerts. Representatives for the Armory are requesting that whatever monetary amount is owed to them be decided at trial.

According to The Alt, a separate suit was filed against Migos and Albany Basketball & Sports Corporation by Sharome Ross, who was an attendee at the 2015 show. Ross asserts that he “was attacked and assaulted by persons who were in attendance at the same show,” and endured “serious permanent personal injuries...caused solely by reason of the negligence of the defendants.”

The venue claims Migos is known for its bad behavior, and for violence and lawlessness.
