Four people were shot around 2:15 a.m. this morning at Plush nightclub in Arlington.
Police say they responded to the scene after a "mass exodus" of people. Upon entering, officers discovered three people had been shot.
They were transported to a local hospital. One victim is in critical condition while two others are stable.
A short time later a fourth victim arrived after driving themselves to the hospital. That victim had a cut and is in stable condition.
The shooting took place from inside the nightclub.
Detectives are interviewing witnesses and a full investigation is underway.
