Police are questioning two people as they investigate a suspected murder in Dunlop.
A 56-year-old woman was found dead in a Dexion Place home about 5.40pm, and police say the nature of her injuries meant the death was being treated as a homicide.
They have established a crime scene and forensic services were examining the area on Friday night. Ambulance paramedics were also called to the scene.
"Due to the nature of the injuries, the death is being treated as a homicide and is currently being investigated by detectives from ACT Policing Criminal Investigations," police said in a statement.
Station sergeant Joanne Cameron said police found the woman in her home.
"About 5.40 this afternoon, police were called to a residence in Dunlop on Dexion Place in relation to checking on the welfare of a resident," she said.
She would not say whether any one else had been in the house at the time. She would also not say who called them, saying the investigation had only just begun.
"Over the coming days, those sort of details will be able to be released," she said.
"There is a man and another woman assisting police with their inquires, but at this stage I can't comment any further."
Police closed Shoobridge Circuit and Fitton Close to traffic on Friday night and said they expected it to be closed for some time. Local residents were still being allowed through.
A resident who lives nearby and asked not to be identified said it was generally a peaceful suburb, and children often rode their bikes outside the home.
"It's a bit distressing," he said.
"Generally, it's a lovely suburb to live in. It's not a nice thing."
However, he said there had been a murder-suicide just a few blocks away in July 2010.
Police asked anyone with any information about the incident to contact Crime Stoppers on 1800 333 000 or at act.crimestoppers.com.au.
