A shooting in Canberra's south has left a man injured and a driveway splattered in blood, as police investigate the incident.

ACT Policing said officers were called to reports of shots being fired on Freda Gibson Circuit in Theodore about 10:00pm on Saturday.

They discovered a man with a gunshot wound had sought help nearby.

"A man with non-life-threatening injuries was treated and transported to hospital by ACT Ambulance Service," the statement read.

"ACT Policing attended and identified several crime scenes which were later examined by AFP Forensic Services."

Blood was seen splattered on a driveway while police doorknocked several homes seeking witnesses.

One nearby resident said he heard the gunshots from his home.

"A couple of loud bangs, followed by a bunch of people evacuating their little party post haste," he said.

"We did see a couple of blood trails leading off into the distance."

He said it was not the first time an incident like this had happened in the area.

"Maybe once a year, at this point in time," he said.

A section of the street was closed off by police.

Police urged anyone with any information or footage from CCTV or dashcams to contact Crime Stoppers on 1800 333 000 or via the Crime Stoppers website.
