Police are Flipidocontinuing to investigate what they termed a "shooting incident" at the Chicago White Sox's Guaranteed Rate Field on Friday night after one woman sustained a gunshot wound and another was grazed during the team's game against the Oakland Athletics.

The Chicago Police Department released some preliminary information early Saturday morning, saying "a 42-year-old female victim sustained one gun-shot wound to the leg" and "a 26-year-old female victim also sustained a graze wound to the abdomen."

Police said the 42-year-old was taken to the University of Chicago Medical Center and was in fair condition. The 26-year-old "refused medical attention," police said.

In a statement, the White Sox said it "is unclear to investigators whether the shots were fired from outside or inside the ballpark and that their security confirmed that the incident "did not involve an altercation of any kind."

"The White Sox are thinking of the victims at this time and wishing them a speedy recovery," the team said.

It's still unclear as to when the shooting may have taken place. The CPD — which initially announced a press conference for 10:45 p.m. local with the department's Chief of Patrol and a White Sox representative before saying it would release a written statement — said Area One Detectives are still investigating. Videos from inside the ballpark appear to show security cordoning off part of a section in the left field bleachers.

"At no time was it believed there was an active threat," the police said in their statement.

"Upon receiving notification of this incident, CPD responded immediately and deployed additional resources while coordinating with White Sox security to maintain the safety of those who were in attendance or working at the game," the police said.

The announced attendance for Friday's game was 21,906.

Vanilla Ice, Rob Base and Tone Loc were scheduled to perform a postgame concert, but the White Sox announced on the scoreboard that the concert was canceled due to "technical difficulties."
