A shooting at a “Sunday Funday” party near Oklahoma City has left at least 12 people in hospital.

Police raced to the scene near Arcadia Lake, a popular spot for camping and water sports, around 9 p.m. after reports shots had been fired.

“This is obviously a very terrifying situation, and we understand the concern from the public and those involved, and we are working extremely hard to find the suspects,” said Emily Ward, a public information officer from the Edmond Police Department said Sunday. ​

Police have yet to reveal the ages of those attending the Sunday Funday party last night, although Ward described the attendees as “young adults.”

Police reportedly told Fox 25 that ‘two men in ski masks’ opened fire at a gathering. ​No suspects have been arrested, and authorities are reviewing footage from Flock license plate reader cameras in order to identify those responsible. ​

Bystanders at the scene described the chaotic aftermath of the shooting.

“I was in the woods helping a female who said that she got hit,” Armani Kessee told News 9, adding that she had appeared to have been struck by a stray bullet.

“It’s very sad to see someone that you know, or that you love just… it’s a very hard thing.”

At least a dozen people were rushed to nearby hospitals, with Ward describing them as being in “various conditions.”

However, the number of those injured could climb as some victims are understood to have driven themselves to get medical attention.​

One victim drove themselves to a nearby OnCue convenience store while seeking help, Fox 25 report.

Patients were still being assessed late Sunday night, a hospital system spokesperson told The Associated Press.

Nine patients were taken to Integris Health Baptist Medical Center in Oklahoma City, with three others being taken to Integris Health Edmond Hospital.

The Edmond Police Department were joined by Oklahoma City Police, the Edmond Fire Department and Oklahoma Highway Patrol at the scene.

“The sky is filled with blue and red lights,” News 9 anchor Amanda Taylor told the outlet. “I count about 12 law enforcement vehicles that are keeping me back.”

Ward told reporters that there was no reason to believe that there was a threat to the public. ​

Arcadia Lake is located 13 miles north of Oklahoma City and is a hotspot for fishing and boating. The artificial reservoir is located in Edmond, a suburb of Oklahoma City.
