Police are investigating the death of a woman after her body was discovered inside a home in Bacchus Marsh, west of Melbourne, early Wednesday morning. A 75-year-old man has been arrested in connection with the incident and remains in police custody while investigators work to establish what happened.

Emergency services were called to a property on Connor Street shortly after 3:30am after concerns were raised about the occupants. Police subsequently located the woman inside the home. She was unable to be revived and was pronounced dead at the scene.

A 75-year-old man was also located at the property and was taken to hospital under police guard. His injuries were described as non-life-threatening. Police believe the man and woman were known to each other.

Investigators have established a crime scene at the property as detectives examine the circumstances surrounding the woman’s death. Specialist police are expected to assess evidence from the home and speak with people who may have information relevant to the investigation.

At this stage, police have indicated that they are not seeking anyone else in connection with the incident. The investigation therefore remains focused on understanding the relationship between the people involved and determining the circumstances that led to the woman’s death.

The woman has not yet been formally identified. Her death will be investigated by detectives, with further information expected to be released as inquiries progress.

The arrest does not mean the man has been found guilty of any offence. Police investigations are continuing, and any potential charges will depend on the evidence gathered by investigators.

Bacchus Marsh is located around 50 kilometres west of Melbourne and is part of the Moorabool Shire. The incident has drawn attention in the local community, particularly because it occurred during the early hours of the morning at a residential property.

Police are continuing their investigation and are expected to provide further updates as forensic examinations and inquiries are completed. Members of the public with information relevant to the case may be asked to contact investigators.
