Police were called at about 2.15am, and arrived to find two teenagers, aged 17 and 18, cable-tied at the house. They were visibly injured after being struck with a baseball bat, and police say a rifle was also pointed at them.

The teenagers were taken to hospital for treatment, but are not understood to have suffered serious injuries. Police subsequently searched the house, finding and seizing two rifles, which were both registered. Residents of the home told police the violence was part of an ''ongoing dispute'' between the two parties.

A 48-year-old man and an 18-year-old man are still assisting police with their inquiries.

Tuggeranong police station officer in charge Acting Superintendent Daryl Neit said police were still gathering all the relevant facts on the cause of the dispute. Superintendent Neit said the use of the rifles was worrying.

''It is a matter of concern to us that firearms have been mentioned and involved, and any time they are we take it seriously, of course,'' he said.

''We've become involved, we're piecing together everyone's story … and from those facts we will decide on what charges will be laid.''

Many Hocking Place residents were surprised to hear details of the violent episode on Tuesday.

There were signs of vandalism at the front of the home, with the rear windscreen of a green Holden Barina smashed and taped up. One neighbour said the vandalism was rumoured to have sparked the dispute, but Fairfax Media has not been able to confirm those claims.

The home's occupants have lived in Hocking Place for more than 20 years, according to one resident, and had never caused any problems. Another neighbour said the street was generally quiet and peaceful, aside from acts of vandalism on and off for the past few years.
