This measure is possible only within the framework of Police cooperation, not within International Judicial Cooperation (the measure is not about gathering of evidence but an arrest of a person). It allows foreign Police authorities to continue pursuing a perpetrator who crossed the Czech state borders. The foreign authority must immediately inform Czech authorities after crossing the border and terminate the pursuit immediately after being instructed to do so by Czech authorities. European Arrest Warrant must be sent immediately after apprehending the pursued person (the international treaties - the SIT or bilateral ones - can stipulate the time limit for a delivery of the EAW).
