Suspicious blaze destroys Tas home

A house has been destroyed and another has been damaged in a suspicious fire in Tasmania.

The fire started in the back of the Housing Tasmania home in Glenorchy and while the cause has not been determined investigators say it is suspicious.

The home was destroyed while a neighbouring home was damaged when the fire spread to its roof cavity.

The damage bill for both houses is estimated at $250,000.

No one was at either home at the time of the fire, which started about 4.50am (AEDT) on Saturday.
