Two British tourists were barred from entering America after joking on Twitter that they were going to 'destroy America' and 'dig up Marilyn Monroe'.

Leigh Van Bryan, 26, was handcuffed and kept under armed guard in a cell with Mexican drug dealers for 12 hours after landing in Los Angeles with pal Emily Bunting.
