Four PSNI officers have been suspended and four more repositioned as a result of an internal investigation into alleged misbehaviour.
The inquiry is linked to mobile phone video footage which allegedly shows PSNI officers driving inappropriately at a number of locations and also has images of an officer drawing a weapon inside a police station in contravention of police regulations.
The footage shows what appears to be PSNI vehicles spinning wildly with tyres smoking in a "donut" manoeuvre.
The videos captured a number of alleged incidents both within police grounds and in public areas.
It is understood all the officers were members of the service's special firearms unit
