A Morgan Wallen concertgoer is accused of urinating on a man and members of his family during the country singer’s performance at M&T Bank Stadium in Baltimore, Maryland, on Saturday, July 18.

Troy Grevelding alleged to TMZ on Monday, July 20, that a man sitting behind him, his wife, brother and 8-year-old niece exposed himself and urinated inside the venue, splashing him and his family in the process.

Grevelding shared videos on Facebook of him talking to authorities at the event, describing the incident. He claimed that police initially told him that they could not arrest the man because they did not witness the incident.

TMZ reported that the Maryland Transportation Authority Police are investigating the incident. The department told TMZ that it was “aware of this incident and the video that is on social media. There is an active and open criminal investigation into this matter.”

In an interview with Fox Baltimore on Monday, Grevelding alleged that the man was talking loudly on his phone and bumped into him several times before the purported incident.

“I literally feel something on my leg. My wife feels something on her leg,” he said. “My wife says, ‘Whatever that gentleman is doing is all over my leg.’”

Grevelding claimed he looked behind him and saw that the man had his “genitalia hanging completely out, and he’s urinating all over the back of my seat, my wife’s leg, my leg, my niece, and he’s looking at me, saying, ‘It’s good, bro. It’s good.’”

“At that point, I kind of grabbed him, pushed him back, and said, ‘What the eff are you doing? You’re pissing all over me,’” Grevelding added.

“After talking with local officials and my team, there is no choice but to cancel tonight’s show due to severe adverse weather conditions expected throughout the rest of the day and night,” he said in a statement at the time. “Safety for my fans and crew is the highest priority. Refunds available at point of purchase.”

However, Pittsburgh Mayor Corey O’Connor claimed there was “no contact” from Wallen’s team to his office.

“There was no contact to Public Safety or my administration, so however the artist and his team picked to not have the show, that was on them,” O’Connor said on KDKA Radio, according to Audacy. “If you’re going to say that you consulted … that’s one story. We, again, had no record of that, from public safety director all the way down.”
