US police are searching for a man suspected of carrying out a double slaying before shooting and injuring two police officers near Oklahoma City.
The officers were shot on Sunday night as they responded to a report of shots fired in the town of Wellston, 35 miles north-east of the city, according to the Lincoln County Sheriff's Office.
The officers' injuries are not life-threatening, and both are expected to be recovering at home soon.
The sheriff's office said one person was arrested after the shooting but that a second suspect, 38-year-old Michael Vance, stole a patrol car and remains missing.
Oklahoma County sheriff's office said Vance is a suspect after two people were found dead at a home in Luther, about eight miles from Wellston.
Vance reportedly posted two videos on Sunday night on Facebook Live documenting his run from police.
In one video, a man wearing a baseball cap says he is about to steal another vehicle and that it's "gonna be intense".
In another, the same man says: "Letting y'all know, look, this is real" before panning across the vehicle to show a long gun on the passenger seat.
He said: "If you want to know what's up next, stay tuned to your local news."
The Oklahoma Highway Patrol said authorities believe Vance is driving a silver 2007 Mitsubishi Eclipse with an Oklahoma licence plate of 943LQQ.
