You may already know, but in case you dont, it would seem we have a child abducter in the area, there is a grey van and a green BMW (no more info) working together, they have attempted to abduct a brother and sister in the barnards green area, the night before last, thankfully they did'nt succeed.
The only info these kids have said, is first the van stops next to the kids, makes an exuse to talk to them, while the bloke behind in the BMW attempts to take them (presumably throwing them in the back of the van.
I expect it will be in the gazette shortly, but in the meantime you could spread the word.
