Two police officers were shot and a suspect was critically injured in a shooting at a hospital today, police in the US said.
Police spokesman Jacob Bettin said the officers suffered minor wounds in the incident at Creighton University Medical Centre in Omaha, Nebraska.
Authorities have not released the names of the officers or the suspect.
The shooting happened inside the hospital, Mr Bettin said, but he would not say where. He said investigators were interviewing several witnesses.
Omaha television station KETV reported that witnesses said the shooting occurred in or near the cafeteria.
Investigators were checking to see whether the suspect was connected to an early-morning incident in suburban Ralston, Mr Bettin added.
Omaha television station WOWT said officers had been chasing a man sought in a domestic dispute, but they ended the chase when it reached dangerous speeds. The vehicle later crashed, police said.
After the hospital shooting, police and security officers were stationed outside and Mr Bettin said the hospital remained in partial lockdown to protect the crime scene and evidence.
Creighton University Medical Centre is one of two trauma centres in Omaha.
