Established by Article 62-2 of the Code of criminal procedure, police custody is a detention measure decided upon by a law enforcement officer, under the control of the judicial authority, whereby a person reasonably suspected on one or more grounds of committing or attempting to commit an offence punishable by imprisonment is held at the disposal of investigators. Such a measure must constitute the sole means of achieving at least one of the following objectives: 1° Enable the execution of investigations requiring the person's presence or participation; 2° Guarantee that the person is brought before the Public Prosecutor so that the latter can determine what action should be taken on the investigation; 3° Prevent the person from tampering material evidence or proof; 4° Prevent the person from pressuring witnesses or victims as well as their family or relatives; 5° Prevent the person from consulting with other people who are likely to be fellow perpetrators or accomplices; 6° Guarantee the implementation of measures aimed at ending the crime or offence. Police custody is pronounced for 24 hours and may be extended up to 48 hours by the prosecutor's office and, for certain crimes and offences, it may be extended up to 96 hours - and even six days for terrorism cases. The person in police custody is entitled to a right to information on the offence for which s/he is being held and on his/her rights during the measure, the right to notify next of kin (relatives, employer or consulate), the right to a medical examination and the right to remain silent and to legal counsel. S/he is placed under the protection of the gendarmerie or police under the conditions set out 19 Customs are authorised to implement two deprivation of liberty regimes: customs holding and, within judicial customs departments, police custody. 31
