THE sound of gun shots rang out in the middle of the night on a street in south west Sydney.

About 11pm police responded to reports of gunfire on Townsend Street in Condell Park with no apparent target.

Two sides of the road were blocked off while police searched for any signs of the shooting uncovering a bullet cartridge in the backyard of a home.

No damage was done to the house and no injuries were reported.

Investigators are appealing for anybody with information to come forward.
