1Judicial police officers and agents take measures so that traces and items pertaining to the criminal offence are recorded and preserved and the crime scene and items are not altered until the prosecutor intervenes, when he/she has confirmed his participation.
2When there is a risk that traces and items might alter or get lost and the prosecutor may not intervene urgently, judicial police officers shall conduct the indispensable investigation actions and, if it is the case, shall sequester the material evidence and items connected to the criminal offence.
