Police announced in a statement Friday that nine officers in a Dallas suburb have been fired for reporting traffic stops they never conducted.

Officials said that three officers resigned before the investigation was finished and four others are still under investigation.

The officers had been suspended in May after a review of officer activity in the field identified several individuals who claimed to have made traffic stops that actually never occurred.

The officers who have been fired can appeal the decision of the department.

Officials said no fictitious citations were issued according to the investigation.

Why the traffic reports were falsified was not indicated.
