The Australian Federal Police have admitted providing wrong information to a Senate committee, conceding Peter Dutton was not briefed on specific details about a foreign bribery investigation into an Australian businessman whose company was later awarded multimillion-dollar detention centre contracts.

Senior AFP officer Neil Gaughan told a Senate estimates hearing on Friday that the answer police provided to a question on notice about Mr Dutton’s knowledge of an investigation into Mozammil Bhojani was incorrect.
