A cannabis farm was discovered in a mansion house which once hosted a ball for King Charles.
North Wales Police executed a warrant at the historic Plas Glynllifon mansion, near Caernarfon, Gwynedd, on Tuesday and found a cannabis farm that a superintendent described as a “significant grow”.
Supt Arwel Hughes told the BBC: "We uncovered a grow, which was on the top floor of the building. We estimate around 12 rooms with grows in them and they were fairly mature plants.
"There's lots of information to process today and lots of forensic work to consider, and lots of other digital matter that we are looking at.
"I'm quite confident we can get to a point where we can make some arrests.
"Clearly, the electrics are being manipulated and lots of water supply being diverted inside and the property itself is in various states of disrepair."
According to the website for the country park gardens which surround the manor house, it was built in the 1830s and is now Grade I-listed.
It describes the home as a: “A grade I listed building formerly belonging to Lord Newborough that once held the ball of the investiture of The Prince of Wales, now King Charles III.”
The investiture gave Charles the title of Prince of Wales and took place on 1 July 1969 at Caernarfon Castle. Plas Glynllifon then hosted the associated ball.
The website states the house and its 16 acres of gardens are privately-owned.
In a statement, North Wales Police said on Tuesday evening: “We can confirm that earlier today, Tuesday 7 April, North Wales Police executed a Misuse of Drugs Act warrant at Plas Glynllifon, near Caernarfon.
“Officers will remain at the location for several days while enquiries continue. We are asking members of the public to respect the police cordon as officers carry out their work.”
