Which prison

[Rich83]

Does anyone know which prison operates on the frequency 451.1000

[iceboy]

i have this feeling it is nottingham prison..because it's so load and clear to me..could be wrong because there is also sudbury in derbyshire and that might get my vote

[jack_sparrow]

i always assumed that was Rampton prison?
