A Wanganui woman claims she was refused service and forced to leave a city dairy after being mistaken as a gang member because of a T-shirt she was wearing.
Vilia Ngawaka says she will lay an assault complaint with police and write to the Human Rights Commission over the dairy owner's actions.
Police said they had not yet received a complaint from the woman.
Ms Ngawaka works at the Wanganui Riverboat Centre and on Saturday was heading home when she called into the Dublin St Dairy to buy a sandwich and a drink.
She was wearing a red and black striped T-shirt. "I had just grabbed the drink and was standing in front of the shelf that has cakes, slices and usually sandwiches on it."
