Two men have been found dead in a Canberra suburb with police refusing to rule out bikie gang involvement.
Police and ambulance officers found a man dead in the front yard of a home in Couchman Crescent, Chisholm after responding to a call for assistance at 3:10pm today.
The second man was later found dead in the rear yard of the same home.
A third man was taken from the scene and is being questioned by police.
It is believed the man is one of two brothers who live at the house.
A firearm was found one the premises, police say.
"One man was found in the front yard of the house and the other man in the rear yard," an ACT police spokeswoman said.
"A firearm had also been recovered from the scene," she said.
But police would neither confirm or deny the incident was bikie gang related.
"We are looking at all possible circumstances surrounding this incident and that will include any possible associations that these persons may have had with any groups," the police spokeswoman said.
The quiet suburban street remains cordoned off however police have allowed traffic through nearby streets.
Mick Schimizi, who was working on a roof nearby with a cordless drill, says that he heard the first shot but thought it was a nail gun in his car.
"We thought it could have been the cartridges, we walked outside later and there were police all over the place," he said.
A resident of street, Bryan Perry, said he was shocked by the incident.
"All the neighbours knew other," he said.
Another neighbour, who lives adjacent to the crime scene but does not wish to be named, said while there were motorcycles in the area he believed the suburb was gang free.
"There's some bikes around here but I don't think (it's) anything gang related," he said.
"We've been here for 19 years and haven't heard nothing like that.
"We're just peaceful people here. Everyone sort of minds their own business.
"When you first hear about it you think the bikie gangs are coming around here now, apparently it's not that."
The man was home at the time of the shooting but said he didn't hear any disturbance.
Territory Investigations Group officers were investigating the circumstances surrounding the deaths, but so far no one has been charged over the incident.
"We've got one person assisting us with inquiries and being interviewed by police but no one is in custody as yet," the police spokeswoman said.
