The blaze destroyed the luxury home in Northwood, with police appealing for information since the incident.

A raid has been carried out in the Blue Mountains on Wednesday, resulting in the arrest of a 69 year old man and also seizing a vehicle.

While a 20-year-old man was arrested in Punchbowl, in Sydney's West a short time later.

It comes two weeks after NSW police's arson squad issued a call for info after failing to find evidence on leads.

Police released footage last month of the Northwood street the night of the fire, calling witnesses who spotted a van leaving the area to contact detectives.

Specialist Fire and Rescue NSW sniffer dogs picked up traces of a substances used to spread the fire, found amongst the ruins of the property.

Prior to the blaze tearing down the home, the property was one of the largest privately-owned pieces in the city - boasting views of the Sydney harbour.

Detectives are set to address the media on Wednesday afternoon.
