Three people have been arrested following alleged extortion of shoppers by security at an Auckland supermarket

A woman says she was accused of shoplifting in January, where guards demanded she pay almost 400-dollars before threatening more fines.

Five victims filed complaints.

Police say men aged 23 and 39, and a 19-year-old woman will appear in the Manukau District Court on Wednesday.

They're facing multiple charges, including demands with intent and obtains by deception - which carries a maximum seven year prison sentence.
