There's been a very visible police presence in Manchester city centre the past few days (bit like having the Labour party conference back!) and there's something a bit odd going on on one of the roads near me. It's a dual carriageway and on the way home from work yesterday I hit a bad traffic jam where there isn't usually one and the hold up seemed to be caused by several police and vans/cars/bikes on the other side of the road. They'd coned off one lane of traffic and were letting cars through slowly a few at a time. On the way in to work this morning I was on that side of the road and they were still there. I didn't see them pull anyone over but there was one car that had obviously been pulled over. Coming home today they are still there and seemed to be searching the boot of a car and still just letting people through slowly. I guess they're doing spot checks or something but there are at least 10 police officers there, a few vans, a couple of cars and a few bikes.
