It is poorly punctuated, but is asking the police to remove the notice.

I think the police are being asked not to loiter (presumably whilst eating doughnuts)
 

The only other interpretation that I can offer is that it is an instruction for the police to remove the notice.
They obviously have not complied!
Having re-read Ben's comment I realise that this is what he said.
Public loitering is surely less harmful/annoying than public eating of doughnuts anyway.

Perhaps it should say
"No eating of donuts
Police will take donuts".
 

I gather that you received the parcel.
