47. To execute a warrant of arrest, a person may enter any place where he has reasonable grounds to believe the witness he has been ordered to arrest is to be found, in order to arrest him.
Before entering the place, he shall give a notice to a person in the place of his presence and of the purpose of his presence, unless he has reasonable grounds to believe that that would allow the witness to abscond.
