The term apprehension is used to designate the act by which a person is detained in a situation of possible crime or actual crime. The apprehension is carried out through the different police forces chosen to carry out such activities and it also has to do directly with the judicial sphere since a judge can order the apprehension of a person who until now is free as a means of precaution against the possibility of the responsibility of that person in a crime or offense.
Apprehension is a broad term that can be used for people as well as things or merchandise. Thus, when an illegal merchandise is found in the customs control places, it can also be apprehended, which means that it is retained by the authorities and responsible officials in order to prevent it from entering the territory (for being dangerous, for For example, as happens with narcotics) as well as considering that the passage of the same would allow fraudulent commercial actions to be carried out (for example, the entry of products that have not paid taxes or adequate rates).
In either case, the apprehension is showing us that the central object of the matter is arrested and detained by the authorities related to the activity. Thus, a person cannot be apprehended by anyone else because that would qualify as kidnapping or breach of the person's freedom. The apprehension carried out by the police forces or by any other competent authority is justified insofar as it is considered that it is carried out for the good of the rest of society.
The apprehension of a person can end both in eventual freedom (if it is proven that he is not responsible for the crime or charge that is imputed to him) as well as in effective and permanent prison (if the interference of that person in the act is proven by which is being charged). In any case, it is important to make it clear that apprehension is that stage prior to final and permanent imprisonment that a person may have to face if accused of a crime.
