The incident unfolded in late February when the two girls, aged 16- and 17-years-old, decided they wanted to travel from their hometown of Borås in western Sweden to Malmö, 285 kilometres to the south, reports the Borås Tidning (BT) newspaper.
In order to pay for the joyride and accompanying shopping spree, the girls stole a safe containing 10,000 kronor ($1,300) in cash which belonged to the father of the 16-year-old.
The girls then stuffed the safe in a bag and headed to Malmö where they met up with a male acquaintance of the 17-year-old who was supposed to help the girls crack open the safe.
But the acquaintance told the girls he lacked the right tools to open the safe, and instead had to hand it over to someone else.
According to the girls, they never saw the safe again and allege it ended up in the hands of the mafia.
The girls now stand charged with theft, with the younger girl claiming she stole her father’s safe only after being threatened by her friend.
The 17-year-old, on the other hand, alleges they both came up with the idea together.
