Two men claiming to be electrical students have been knocking on doors in Dunedin's student area, sparking a warning from police.
Police were contacted after the pair knocked on the door of a Heriot Row flat at 4.30pm on Tuesday.
They told the female occupant they were electrical students who were looking for men to help them with a study.
Twenty minutes later they did the same thing at a house on Pitt St.
Police said one of the men was a tall Maori or Pasifika man, and the other was a man in his mid 20s with mousy brown hair and a buzz cut.
Anyone with concerns should contact police.
