Eight men have been charged with hundreds of child sex offences against a 13-year-old girl in Australia, including her father who police alleged Wednesday facilitated the horrific abuse over two years.

A hapless teenage thief who allegedly broke into a Perth shop to steal sweets was arrested after a receipt spike sliced through his hand, police said Monday.

The 16-year-old and two others allegedly forced their way into the store on Sunday evening but as the boy tried to jump over the front counter he impaled himself on the spike.
