Police say that hours after a 17-year-old posted photo of a large sum of cash on Facebook, a gang of masked men, armed with knives and clubs, broke into the home of the girl's mother in the country town of Bundanoon, south-eastern Australia.
According to the police, the thieves, who had probably "liked" the picture on Facebook, came to the house of the girl's mother about 11:30 p.m. on Thursday. They wore dark-colored clothing, gloves and had their faces covered. They said they wanted to speak to the girl about the cash on her Facebook page.
But the girl's mother told them they had broken into the wrong house. The girl was not living with her mother. She had taken the photo at her grandmother's house in Sydney at about 4 p.m. the same day.
According to BBC, the girl posted on her Facebook page, a picture of a "large sum of cash" she had helped her 72-year-old grandmother count in her home in Sydney, 120 kilometers (75 miles) north-east of Bundanoon.
The Australian reports the men, unwilling to believe the girl's mother, searched the house and took some cash and a few personal belongings before they left.
BBC reports it was not clear how the men found the address of the girl's mother's house.
Following the incident, the police have released a statement warning people about the risk of posting sensitive information online. The police warned users of social media to take extreme caution when posting photographs and personal information online.
