Hunt for arsonists after fire at Tas home

A fire allegedly lit by a group of teens has caused extensive damage to a Hobart home belonging to a charity.

Police are on Saturday appealing for information about a group of youths suspected of lighting a fire at an unoccupied home belonging to Mission Australia on Goodwins Road in Clarendon Vale.

The youths were seen about 1am on Saturday running away from the scene of the fire, which was extinguished by firefighters but caused an estimated $100,000 in damage.
