The rhino-headed intergalactic police first made an appearance more than 12 years ago to terrorise the Tenth Doctor - played by David Tennant - and his companion Martha Jones (Freema Agyeman) in 2007's 'Smith and Jones'.

And when the Thirteenth Doctor - played by Jodie Whittaker - returns to screens next year, she will come face to face with the brutes once again as they make their long-awaited comeback to the popular BBC sci-fi show.

The Judoon will meet The Doctor in present-day Gloucester, but as of the time of writing, all other details of their episode are being kept under wraps.

Showrunner Chris Chibnall said in a statement: "No! Sho! Blo! The Judoon are storming back into Doctor Who in full force, and the streets of Gloucester aren't safe. If anyone has anything to hide, confess now. The Judoon are taking no prisoners, and will stop at nothing to fulfil their mission! The whole team on 'Doctor Who' are delighted and scared in equal measure to welcome them back: one of many treats we've got in store for viewers next series."

The episode is also set to feature two-time BAFTA nominee Neil Stuke, who has previously held roles in 'Doctor Foster', 'Silk', and 'Silent Witness'.

Chris added: "And we're over the moon (with Judoon), to be welcoming the wondrous Neil Stuke as guest star. We can't wait to show you what happens when his path crosses with the Thirteenth Doctor."

The upcoming 12th season of 'Doctor Who' is currently in production, and is set to air in early 2020, though no exact date has been announced.

The series will see the return of Jodie's Doctor alongside her companions Graham O'Brien, Ryan Sinclair and Yasmin Khan, played by Bradley Walsh, Tosin Cole, and Mandip Gill, respectively.
