Administrative Penalty Act Article 34

The administrative agency may take the following actions against the person who is in the very act of breaching a duty under administrative law:1. To stop the act immediately; 2. To prepare a written record of the act;3. To take actions for the purpose of preserving the evidence, and, in the case of any act of resistance preventing the preservation of evidence, to take compulsory measures to eliminate such resistance in a state of urgency; and4. To establish the identity of the actor. If it is actually impossible to make out the identity of the actor because of his refusal to accept or evasion of checking on his identity despite the making of efforts of persuasion and the state is urgent, he may be ordered to follow the officer to a specified place to have his identity checked. If he refuses to follow the officer to such place to have his identity checked, he may be compelled to do so by the officer in the company of police officers. The compulsory measures taken under the preceding paragraph shall not exceed the degree necessary for the purpose of preserving the evidence or checking on the actor's identity.
