Shanghai Transformers Police?

When we drove back from Wuzhen to Shanghai in January, we encountered the above posted police car. The first time it passed us by, I was like 'wtf?', that can't really be a police car. But then I noticed the siren on top of the car as well as the white licence plate - and got really angry that I didn't take a picture. But our cool driver wanted to get back home quickly or something and passed them a minute later. I was hoping that this would happen and had my camera ready this time.

'Police 1865' it says together with the Transformers logo. I wonder if these guys are just big fans or if their unit really uses that famous symbol as their logo?

Maybe they are trying to catch Edison Chen...
