John Prescott (The Bumbling deputy prime minister in the UK) has 'let slip' that some of the suspects detained in the current alleged terror plot
will not be facing serious charges.
Well today is the day the police have to apply for an extension to detain them further. I believe this is closed / secret session (not open court) but
lawyers still need to present evidence to a judge for the extension to be made. If some are not facing 'serious charges' or charges not related to
the terrorism act then they may well be released with no charge or on bail or possibly even re-arrested for whatever the lesser charges are.
Although they have all been arrested none of them have actually as yet been charged with any crime. So yes you can be arrested and then released
without charge it all laregly depends on whether the crown prosecution service believes a conviction is likely based upon the evidence. At least
that's how it normally works but where terrorism is involved I think they have ways of holding onto you if they really want to.
