Officials at the Emu Plains Correctional Center near Sydney, Australia, announced in January that they had pre-empted a planned escape by two female inmates, ages 32 and 21, after finding a 60-foot length of tied-together sheets in a cell.

Nonetheless, the officials said they were puzzled, in that Emu Plains is a one-story facility, enclosed, wrote the Daily Telegraph, by a "not particularly high" fence. [Daily Telegraph (Sydney), 1-3-2014]
