There's a small brick wall that's fallen over on my street but until now has been laying entirely on the owners front lawn. So I've left it figuring that although an eyesore there is technically nothing to be done about it. I'm now questioning that as over the weekend some kids have started playing with the bricks and left them on the pavement. Pretty sure the house is empty so no one to talk to about it. Is this something I can report. The council (Merton) are generally pretty responsive to various flytipping I've reported in the past, so confident they'd deal with it, if it's a legitimate complaint.
