An 18-year-old man launched a vicious assault on another young man because he thought he was making a move on his sister.
Senior Sergeant Anthony Bond, of Dunedin, said officers were called to reports of an assault at an Octagon bar at 12.05am on Sunday.
A 19-year-old man was waiting to get into the bar with his friends when the 18-year-old approached them.
The 18-year-old started pushing them around, Snr Sgt Bond said.
“He believed [the 19-year-old] made a move on his sister,” Snr Sgt Bond said.
