A Warrant for the Arrest of a Witness in a Grand Jury Proceeding (Under Seal) is a document issued by a judge or magistrate, allowing law enforcement officers to arrest a witness for failure to appear in a grand jury proceeding. The warrant is sealed to protect the identity of the witness and the grand jury proceedings from the public. There are two main types of warrants for the arrest of a witness in a grand jury proceeding: 1. Grand Jury Arrest Warrant: A Grand Jury Arrest Warrant is issued by a judge or magistrate for a witness who fails to appear in a grand jury proceeding. The warrant authorizes law enforcement officers to arrest the witness and bring them to the court to appear before the grand jury. 2. Grand Jury Subpoena: A Grand Jury Subpoena is issued by the court for a witness to appear in a grand jury proceeding. The subpoena orders the witness to appear at the specified time and place. If the witness fails to appear, a Grand Jury Arrest Warrant may be issued.
