SA teens charged with starting bushfire

Two teenagers have been charged with intentionally starting a bushfire in greater Adelaide.

A grass fire was spotted in Gillies Plains just before 1am on Tuesday.

Police say they found the teens close by with a lighter.

The 17-year-old girl and 15-year-old boy, both from Gillies Plains, have been charged with two counts of intentionally causing a bush fire.

Police will allege the youths also lit another fire on Monday night on Valiant Road Holden Hill.

The pair have been refused bail and are expected to appear in court later on Tuesday.
