TULSA, Oklahoma - Police say a knock at the front door led to a shooting outside an east Tulsa home early Saturday.

Officers were called to a home in the 14300 block of East 36th Street just after 3:30 a.m. in reference to shots fired.

The homeowner, who was in the garage playing pool with some friends, told police heard a loud knock at the door.

He told police he answered the door with a gun in hand out of concern for his safety.  As he opened the door, he said the suspect saw the gun and ran towards a nearby car.  He said the suspect also produced a gun and fired it in his direction. 

The homeowner told officers he returned fire with one shot apparently hitting the driver of the suspect's vehicle.

Police say a short time, the driver showed up at a Broken Arrow hospital suffering from a gunshot wound.  They said he is expected to be OK.  

Tulsa police continue to investigate and say so far, no one has been arrested.
