A Christchurch woman was left with serious facial injuries and multiple fractures after she was allegedly stomped on during a vicious attack in the city on Saturday night.
The 26-year-old woman and her brother were assaulted in Woolston about midnight on Saturday, police said.
Senior Constable Mike Phillips said a man and two women were understood to have started assaulting the victims when they reached the corner of Ferry Rd and Oak St.
"The three assailants have continued the assault until the group was near the corner of Ferry Rd and Radley St.
"They are then reported to have fled the scene and got into a grey Subaru station wagon, possibly a Legacy or similar model, that was parked on Radley St and driven south along Radley St."
