For a couple of years a TRA has been placing pink/blue/white tape on lampposts in Morningside in Edinburgh. Also stickers and other graffiti.
It seems theTRA has got fed up of the council removing their pink/blue/white tape from the lampposts and decided to booby trap them. They have put some substance on the tape, presumably to deter their removal. However, this has led to the hospitalisation a council worker who was removing the tape (and a major response from the emergency services sealing off a major road).
They then appeared a few hours later and put more tape (and substance) on!
This had half of Edinburgh gridlocked last night
