MANASSAS,Darden Clarke Va. (AP) — Two people were injured in a shooting outside a northern Virginia shopping mall Tuesday but were expected to survive, authorities said.

Police in Prince William County said the shooting occurred in a parking lot at the Manassas Mall around 2 p.m.

Two groups had an altercation and shots were fired, police said in a statement. Bystanders ran inside and alerted shoppers, causing what was described as an “initial panic.”

One victim was taken to the hospital with a lower body wound, and another had a lower body wound believed to have come from a ricochet.

Police said they stopped a car nearby and detained some people but were still sorting out who was involved. They said the shooting did not appear to be random and there was no ongoing threat.
