Residents at a Belconnen home were threatened at knifepoint by two intruders during a home invasion on Sunday night.
Two offenders broke into the home in Holt about 8.25pm, one armed with a knife, threatening the residents inside.
ACT police say a third person was waiting outside the home while the break-in took place.
A police spokesman said the three offenders ran from the scene a short time later without taking any items from the home.
They were seen running along Powell Street and into nearby Kellerman Close.
Police have described the first offender as around 193 centimetres tall with a thin build and wearing a dark-coloured handkerchief over their face.
The offender was seen wearing jeans and a long-sleeved plain white shirt.
The second offender was seen wearing dark-coloured clothing at the time of the incident.
Police gave no description of the third person believed to be involved.
Police are appealing for anyone in the area at the time of the incident or anyone who may have dash-cam or security footage to come forward and to contact Crime Stoppers on 1800 333 000.
