Morgan Wallen‘s concert at Arrowhead Stadium was delayed by 40 minutes on Friday as police arrested a man at the venue.

Aaron Brown of Winchester, Illinois was charged with a Class E felony of making a terrorist threat in the 2nd degree after threatening to shoot two Kansas City Chiefs players who were in attendance at the concert, according to the Jackson County Prosecutor.

Although the prosecutor did not disclose the names of Brown’s targets, Wallen walked onto the stage Friday with Travis Kelce, Patrick Mahomes and Chris Jones while wearing a Chiefs jersey.

Police detectives and intelligence analysts working at the stadium on Friday were monitoring threats online when they discovered Brown’s post on X. Brown then confirmed to police that he was at the stadium as they located him and took him into custody.

Brown was charged Saturday morning, during which a $15,000 bond was set. Prosecutors requested a $250,000 cash bond.

Wallen is currently on the road for his One Night at a Time World Tour in support of his third studio album One Thing at a Time, resuming Aug. 8 in Las Vegas and wrapping up Oct. 19 in Charlotte, North Carolina.
