The words custody and arrested are not synonymous terms. In every arrest, there is custody, but not vice versa.
Arrest is a mode of formally taking a person in police custody. Whereas ‘custody ‘ merely denotes surveillance or restriction on the movement of the person concerned.
A person may be taken in custody completely or even partially. The concept of being in custody is, therefore, different from that of a formal arrest. Thus it would be seen that in every arrest there is custody but the converse is not true and as such, arrest and custody are not synonymous terms.
