can anyone shed any light on whats this is all about?

Laz doesn't seem very clued up on the law from what he wrote in his instagram post above.

Also are the Met police all of a sudden become Banksy's best mates. The anarcho anti police guerilla graffiti artist Banksy.

If Banksy dumped that fibreglass monstrosity in the street and did a runner after having media publicity shots made. Then Linky saw it dumped there and took it home. He did people a favour as a sudden gust of wind could have blown that fibreglass thing anywhere and caused a bad accident.

If after Linksy took it home, Banksy went back to retrieve his shitting bigfoot statue and found it was gone. He could have reported it lost or stolen to the Met police and had a record of his report to back up he owned it.

If Bankster decided to do nothing and when Linky contacted him by beaming a stencil of a rat into the night sky via a huge searchlight or Morris Marina headlamp and Banksy replied for Linkman to burn it; Linkman has proof that Bankash did not want it back. Plus by not bruning it which is illegal anyway as burning fibreglass objects give off all sorts of toxic smoke and to set fire to it in a garden would have resulted in a visit from the council EHD and police.

So it appears that a lot of time went by and BanksyControl entered Linkmans garden ilegally , trespassing and stole an object which belonged to Linky.

All of the above depends on the timeline of events of course.

So Poop Control issued a certificate of authenticity in order for this pooping bigfoot fibreglass monstrocity can be sold by their pals Smoothybys and Linky is depressed because he had something worth money in todays bizarre realm of money laundering, I mean investing through art and instead of doing what most would have done is to have cut the thing up into sections and hidden each piece in different parts of the world so that there was no chance of ControllingBanksy to get their hands on it without the map hidden in a secure place which only JCVD could access.
