Pair held over Sydney bushfire

Two people have been arrested after a blaze broke out close to homes in Sydney's south-west.

The bushfire was burning out-of-control in Airds, near Campbelltown, and is said to be threatening about 20 homes.

The fire was approximately five hectares in size, and started sometime around 4:30pm.
