A woman has been robbed after her daughter posted pictures of a large amount of cash on Facebook.
The 17-year-old girl was helping her grandmother count her personal savings in their Sydney home at 4pm (AEST) on Thursday when she took a photo of the cash and posted it on her Facebook page.
At 11.30pm on the same day, two men armed with a knife and a wooden club allegedly broke into the Southern Highlands house of the girl's mother demanding to talk to the girl about the money.
The woman told the intruders the girl no longer lived at the house but they searched it and took a small amount of cash and personal items.
No one was injured during the incident.
