I was stopped by a copper the other night..
He advised to be careful and report seeing a blue Toyota Yaris with kids in. He didn't know a registration but advised that they had been involved with wallets, car keys and other items being stolen as well as cars being damaged.
He did give me a direct telephone number but not going to post it here..
It sounds like they have got out a car and joined a group around a car and while guys are distracted have rifled through pockets..
Just passing this information on as the night prior, I did see a blue Yaris with some abusive kids in, where I left the area..
Don't let it put you off, but as always when out, be aware of what is going on around you..
