Good luck Mr Float.
That just sucks!
I had my own version of that recently (though thankfully kites are still here), not so lucky for a bike plus other gear belonging to my sons

All happened around the time a close family member was diagnosed with terminal cancer and a good friend shattered her neck

The A holes also stole a set of house keys and came back the next day, but scampered when my son (who had left the house for 10minutes) came home. (Locks changed the day of break in)
I would not advise anyone to take the law into their own hands but I can see why some might.
Anyway, good luck with scrapping the scum from your world...
