помещать под стражу(. When a person is remanded in custody it means that they will be detained in a prison until a later date when a trial or sentencing hearing will take place. The majority of prisoners on remand have not been convicted of a criminal offence and are awaiting trial following a not guilty plea. If a person is convicted and remanded in custody until a sentencing hearing this is known as ‘Judges Remand'. A prisoner subject to ‘Judges Remand' is no longer entitled to the privileges available to unconvicted individuals and is treated as a sentenced prisoner. – See more at: offendersfamilieshelpline.orgAlexander Demidov)
