Police are investigating after a woman attending the St. Louis Cardinals game at Busch Stadium on Tuesday night was grazed by a stray bullet that presumably came from outside the stadium.

The 34-year old woman was sitting in her seat near the dugout when she was struck.

According to the police report, the woman felt pain in her arm and noticed a small abrasion above her elbow when she removed her jacket, the St. Louis Post-Dispatch reported. The woman went to a first aid station for treatment and contacted an off-duty police officer.

Police said they found a bullet slug "in the immediate area around the victim's seat."

The Cardinals issued a statement on Wednesday: "We are aware of an incident last night in which a fan reported being struck by a stray bullet that presumably originated from outside of the stadium. The fan was treated for an abrasion and a bruise on her arm at first aid and released. She was interviewed by police who are investigating the matter. There is nothing more important than the safety of our fans, and the Cardinals are grateful that no one was seriously injured. We will be sharing more information with the media as further details emerge."

"This further amplifies our yearly message of encouraging 'Fun Without Guns,'" the St. Louis Police department said in a statement. "We know 'what goes up must come down,' and in this case, an innocent victim was struck. The department constantly stresses the importance of safety and responsible gun ownership."

The Cardinals were playing the Milwaukee Brewers and won 2-1.
