Multiple people are dead and others are wounded after a shooting at a Virginia Walmart on Tuesday night, police said.

"We were able to find multiple fatalities and multiple injured parties," Chesapeake Police Department officer Leo Kosinski told reporters at the scene, saying rapid response officers entered the store "immediately" as they arrived.

"We believe it is a single shooter and that single shooter is deceased at this time," he added.

Officers responded to a report of a shooting at the Walmart on Sam’s Circle around 10:15 p.m. and as soon as they arrived they found evidence of a shooting, Chesapeake police spokesman Leo Kosinski said in a briefing.

Over 35 to 40 minutes, officers found multiple dead people and injured people in the store and put rescue and tactical teams together to go inside and provide life-saving measures, he said.

Police believe there was one shooter, who is dead, he said.

They believe that the shooting had stopped when police arrived, Kosinski said. He did not have a number of dead, but said it was “less than 10, right now.”

The City of Chesapeake also said on Twitter that police did "confirm an active shooter incident with fatalities at the Walmart on Sam's Circle.

"Our first responders are well-trained and prepared to respond; please give them space to do so," it added.

News footage showed a major police presence at the scene, with Kosinski saying several officers and investigators were combing through the store and securing the area.

The exact number of fatalities remained unclear, but CBS affiliate WUSA said police said they believed no more than 10 people were killed.
