Up to 1,000 gardaí could be investigated over the recent breath test controversy.
According to today's Sunday Independent, an investigation is on the cards after a report found that 1.5 million fake tests were recorded.
Justice Minister Charlie Flanagan has referred to the scandal as a "very dark chapter" in the history of the Gardaí.
Minister Flanagan says he will have a zero tolerance approach to Gardaí who knowingly submitted false tests, saying that he is "not ruling in or out any measure", including dismissals.
