A 21-year-old man was shot in the lower leg in the Summerhill Road area of Dunmurry in a suspected paramilitary style assault.
It happened just after 10:25pm.
The man was taken to hospital for treatment.
Inspector McCullough said while enquiries are at an early stage, this shooting bears the hallmarks of a paramilitary style assault.
“Those who carried out this barbaric act do not represent the interests of the local community, nor do they contribute anything to it. They use violence to try and exert influence, or gain control of those they claim to represent,” he said.
