Hi Guys. Apologies if posted in the wrong place, but I was hoping for some advice from the any serving Police on the forum. Essentially, my suspicions have been roused about a property that my flat overlooks. There appears to be 30/40 people living in the basement of a Chinese Takeaway/"Massage Club"/Cornershop (it changes every few weeks!) and given the situation I'm a bit concerned that there may be illegal immigrants living there/people trafficking etc. I'm not an immigrant or foreigned basher, but after an incident last night I'm genuinely concerned for their welfare. My question therefore is: Is it appropiate to make a tip-off to the relevant authorities? And if so whats the best route to do this. I have googled it and its pointing me towards phoning Crimestoppers, which doesn't strike me as the best way to go about it. Thanks, Walkyrie.
