Fraser and members of her family confronted 10 teenagers who were trying to break into her daughterâ€™s Sunshine Coast retreat on Friday night. The 71-year-old told Sky News she "annoyed" at the teenager's actions. â€œThis one guy came out of the gate and grabbed me and I grabbed him by the ear and kicked him in the groin and he had to let me go,â€ she said. â€œAnd he threatened my life and I got really annoyed about that and just grabbed him by the ear and by the hair â€¦ we made him lie on his stomach until the police arrived.â€ Two people were arrested following the incident.
