Be aware went to Compton 7pm across the road in pub car par unmarked police looking straight at massage parlour went for a pint but that were watching people go in n out
I am no legal expert however I would be very surprised if they are watching the Chinese place. Firstly they are not a brothel and they know that women go there as well as men. Secondly they would not find any evidence of a brothel if they raided it, condoms, lube, drugs etc.
You will probably find that they were watching the laundrette or that particular corner is well know for them to sit on the pub car park for speeders and ANPR checks. Lots of boy racers use that route to Bridgnorth.
I could of course be totally of the mark I believe West Midlands police are about to embark on a major clampdown and before I get the superstitious amongst you questioning it. I read about it in a local paper.
