Tony Abbott's most senior aide, Peta Credlin, has chastised a news photographer for taking pictures of her after a media event and demanded all images taken of her be deleted.

The Prime Minister's chief of staff took umbrage at an AAP photographer at a police station in Melbourne on Friday.

Ms Credlin, who has stayed largely in the shadows since Mr Abbott's leadership crisis in February, insisted she was in a "secure area" of Endeavour Hills police station, and asked photographer Tracey Nearmy to delete a picture.

"Sorry, I would like it deleted please. I would like it deleted," Ms Credlin told Nearmy.
