A woman who died from her injuries after a disturbance at a suburban house in Perth's north had her three children home at the time, police say.

Homicide detectives are investigating the woman's death after police were called to a house in Clogher Street in Ridgewood, 35 kilometres north of the city's CBD, about 6:15am.

They were told a woman in her 30s had been seriously injured and taken to hospital, where she later died.

Acting Detective Superintendent Brett Ranford said the man who took the woman to hospital was in custody and helping police with their inquiries.

"However it is early into the investigation and we are still trying to establish what his role was and his relationship was with the deceased," he said.

A cause of death has yet to be established.

Police are asking anyone with information or who saw or heard anything suspicious on Clogher Street to contact Crime Stoppers.
