Being followed...

[WILDB]

Just a forewarning that this is a long story.

Driving home from work last Monday night about 10pm in my mums car I saw this white VT run a stop sign and almost got collected by a Corolla but then drove off so I thought nothing of it. Traffic was moving slowly (caused by this VT) other cars were overtaking so I pulled out to overtake and this guy swerved into my lane forcing me to brake to avoid an accident so I flashed my high beam to let the driver know they had almost caused an accident in case they weren't aware. The Commodore then turned down a side street then pulled out again and tailgated me extremely close for approx 9km and taking every turn I was taking. I then thought this guy was following me so I drove quickly up the windy part of road on the way back up toward home and thought I had left this guy behind. Still being a bit cautious I turned down an unlit side street and turned the lights off, ducked down and waited for the car to go past - which it did a couple of minutes later. I waited about 5 min before driving home and didn't see this car again.

On Tuesday night driving in mums car again from work at about 9:30pm the same car comes flying out of a sidestreet behind me tailgating again until this twisty section of road where I left them behind and pulled into another unlit side street and waited for about 10min after they had driven past this time - I then drove home and didn't see the car again.

For the rest of the week I was driving my XR and didn't get followed and had forgotten about the whole thing until last night.

Yesterday night I was picking up my younger sister from a friends house in my mums car and suddenly this VT flew out behind me again so I took a different route and eventually found a well lit area and stopped in the middle of the road - there is always a dolphin torch in the car so I grabbed that and hopped out of the car shining it at the driver so I could get a good look. The driver then nailed it off but luckily I got the rego number and a good look at the driver. It was definately the same car all 3 times because I noticed all 3 times it had the right tail light blown.

My main concern is that my mum will be driving along and get followed and I don't want this person to know where we live.

Judging by all that has happened do you think that I would have grounds to report this to the Police?
