At least 10 people were injured in a shooting at a party held near Arcadia Lake, Oklahoma, on Sunday night. According to Edmond police spokesperson Emily Ward, authorities were alerted to the incident around
9 p.m. after receiving multiple reports of gunfire.
At least 10 victims were transported to local hospitals, while others may have sought treatment on their own. Ward noted that the victims were in
“various conditions.” As of now,
no arrests have been made, and authorities are working to determine what led to the shooting.
Despite the distressing event, Ward reassured the public that there is no reason to believe there is
an ongoing threat. A significant police presence was reported near the Arcadia Lake Campground following unconfirmed reports of shots fired, with eyewitness accounts citing a heavy influx of first responders, including a large number of police cars and ambulances.
One witness commented on social media,
“Everyone check on your people there was a mass shooting at arcadia lake.” Another added,
“Does anybody know what’s going on out by Lake Arcadia? No exaggeration, we have had probably 30 police cars fly by our house along with multiple fire engines and ambulances.” In the hours following the incident, authorities are continuing to investigate the circumstances surrounding the shooting.
