NSW teens allegedly rob elderly woman

A 75-year-old woman has been dragged along the ground at a shopping centre after refusing to relinquish her handbag to teenage bag-snatchers on the NSW south coast.

The 16-year-old and 13-year-old culprits attempted to take the bag on Tuesday at Warrawong but found the elderly lady tougher than anticipated and a struggle ensued, police say.

The pair eventually got their hands on the bag and fled, only to be arrested by police later in the day.

The woman was not seriously harmed.
