Tulsa Courthouse Shooting Wounds Sheriff's Deputy (PICTURES)

A 23-year-old man is suspected of shooting a Tulsa County Deputy and injuring four others when he fired several shots outside a courthouse in Oklahoma.

Joseph Dennehy opened fire on Wednesday afternoon, shooting randomly outside in the plaza in front of the building.

Hearing gunfire, deputies rushed outside, returning fire. A deputy and a passer-by were hit before the shooter was eventually cut down.

Dennehy lay on the concrete at the scene, bleeding from his upper body.

He was taken to a local hospital, but his condition remains unknown. He has yet to be formally charged.

Both the deputy and the passer by suffered non-life threatening injuries.

Reported by the Associated Press, an Emergency Medical Services spokesperson confirmed that one man was taken to a hospital in critical condition, two others were hospitalized “one in serious and one in fair condition”.

A woman, who was not hit, was treated at the scene for shock.

Glyn Roe, a witness to the shooting, said: "Everybody was running. I was watching it to make sure he wasn't coming into the library, or I would have started running, too."
