Police are investigating a deliberately lit house fire in Gordon this morning which completely destroyed the residence.

Around 7.10am emergency services received a Triple Zero call about a house on fire on the Channel Highway.

The house, estimated at $300K in value, was well alight when reported to emergency services and was completely destroyed by fire before emergency services arrived at the scene.

TasNetworks staff attended and rendered safe the power supply to the house and neighbouring properties.

A 48-year-old man was taken into custody by police near the scene and he is now assisting investigators with enquiries into the circumstances around the fire.

A fire scene examiner from the Tasmania Fire Service attended the scene as part of the investigation and determined the fire was deliberately lit.

Hobart CIB are investigating and would like to speak to anyone with information that would assist the investigation.

Information can be provided to police on 131 444 or Crime Stoppers anonymously on 1800 333 000.
