A resident of the building said he heard screaming at about 4pm and saw multiple police cars arrive at the public housing block on Light Street soon after.

Police said they found a man dead at about 4.30pm after receiving a call from a member of the public.

They would not elaborate on the relationship between the deceased and the man who has now been charged with his murder. They would also not reveal details of how the victim died, or his relationship with the member of the public who called.

They said paramedics had also been called to the scene, but had not been required to treat anyone.

"ACT Policing Criminal Investigations team members attended and examined the scene and will be assisted by AFP Forensic Services," police said on Monday, noting a report will be prepared for the ACT Coroner.

An area at block six of the flats was cordoned off with police tape on Monday night, as officers investigated the scene. They were removing belongings from the apartment about 7.15pm. They remained at the scene shortly after 8pm.

Griffith resident Anthony Croke said he was driving by the street just after 5pm and was startled by the police presence.

"It was upsetting to see because I do a lot of charity work around here," he said.

The accused will face the ACT Magistrates Court on Tuesday morning.

Police are calling on anyone who may have seen anything in the area to contact Crime Stoppers on 1800 333 000 or at act.crimestoppers.com.au.

Earlier on Monday in an unrelated case, police said an autopsy on a woman found dead at the Kingston Foreshore was not suspicious. Police had initially investigated it as a suspicious death, after the 29-year-old's body was found in the early hours of Friday morning.
