Thames Valley Police discovered the plants in some woodland area near Wolvercote Mill Stream and seized and destroyed them, but not before leaving a surprisingly friendly message on a card.
An officer wrote: “Ooops! Sorry we missed each other but feel free to call me on 101 so we can discuss a deal! Lots of love TVP x x.”
The note, which was tweeted out by the official TVP Oxford account, has gone down very well on Twitter.
We can’t imagine they returned the call, though.
