Anyone know the legalities on this?

Just gone outside to find a load of cones lined along the road where my car and bike are parked. Now I've had nothing through the door to tell me works are commmencing etc so I've stacked them up and fucked them off. (I don't like them hanging around over night cos chavs have a habit of lobbing them around)

I'm guessing they are hoping I'll move my car & bike 2moro (not happening) and that people looking to park in there after I've gone will be pit off by the cones. Anyone know if I can get in trouble for leaving the car there even if they want to do something to the road?

The missus is whinging about me moving the cones already so I might have to put them back in a mo for a quiet life
