Hey man, i had my plates stolen a few years back, i know who did it, but thats besides the point. anyway i reported it to cops and had to fork out for another set of plates. what the police did was nothing, and just put a flag on my plates as "STOLEN" so for the next 3 years when driving round, id get pulled up for no reason coz the plates were flagged and harassed by the cops, after a while i got sick of it and blew up at the cops told them i wanted him to go back to the station and remove the flag from my plates, as it was bullshit. I havent been picked on since. i know your pain man, its a pain in the arse, the only thing you can do is pay for replacement plates and get some good secirty screws on there. but if they ripped them off, not alot is going to stop them taking them. being where u live man, i can bet it was some drunk wankers walking home from the clubs or something. thats the usuall story behind it. i can garauntee that they will either be up on somebodys wall as an ornament or disposed of down the road soemwhere in a bush or bin. il keep an ear out anyway for you, but unless police actually go into the place for some other reason and find your plates in there, then i dont like your chances of getting them back.
Cheers
Darren
