Two men have been charged after allegedly impersonating police near Camden on Friday night.
Police will allege three men used blue and red flashing lights to pull over a car from Macarthur Road onto River Road, Elderslie just after 10pm.
The men allegedly drove up next to the car, driven by a 34-year-old woman, and spoke with her.
