UK prison guards unwittingly allowed a convicted drug dealer to grow marijuana in his cell - and even decorate a four-foot plant as a Christmas tree.

Gold-toothed Mohamed Jalloh, 28, convinced jail staff for at least five months that his super-powerful crop was only tomato plants.



He got so cocky he put festive decorations on one to brighten up his cell at Verne Prison in Portland, Dorset in southern England. Eventually he was turned in by a jealous inmate, and guards then identified the plants using Google image search.



"You could see the plants from the grounds as his cell looks on to the education department and communal outside area,” a source told The Sun.



“They were on show for the world to see."



Jalloh is serving eight years for supplying Class A drugs.
