Portland, OR -

Two of the four people shot at a Portland strip club Saturday night remain in critical condition.

The Oregonian reports they are a 26-year-old security guard and the unidentified man who walked into the Mystic Gentleman's Club and opened fire.

Two of the people who were hit, a 31-year-old man and a 27-year-old woman, were treated at a hospital and released.

The suspect was wounded by a man at the bar who returned fire. He's cooperating with police and was not arrested.

Another shooting at the same club in July 2012 left one man dead in the parking lot.
