Two Whangarei friends sprang into action and tried to catch a teenage robber who pushed an 80-year-old woman to the ground from behind and ripped her bag from her grip.
Melena Puru, 34, and her friend Melanie Joyce, 40, both from Hikurangi had just finished their lunch in town and were returning to their car when they saw the bag snatch happen in the Forum North carpark about 1.43pm yesterday.
Ms Puru began yelling trying to alert others in the carpark then went to the aid of the elderly woman while Ms Joyce and another woman pursued the fleeing mugger.
"I saw him trying to yank the bag off her and she was holding on. He just yanked it and pushed her to the ground. I started yelling out 'Hey he's taken her bag'," Ms Puru said.
"I went to help her and she was not saying anything just shaking. Her hands were covered in blood where the stones had broken her skin," Ms Puru said.
