It shall be made in the manner prescribed in 10 Del. C. § 4512 and shall be granted under the conditions prescribed in that statute.

No obligation of secrecy may be imposed on any person except in accordance with this rule.

The court shall afford those persons a reasonable opportunity to appear and to be heard.(4) Sealed indictments. The judge to whom an indictment is returned may direct that the indictment be kept secret until the defendant is in custody or has been released pending trial. Thereupon the prothonotary shall seal the indictment and no person shall disclose the return of the indictment except when necessary for the issuance and execution of a warrant or summons.(5) Closed hearing. Subject to any right to an open hearing in contempt proceedings, the court shall order a hearing on matters affecting a grand jury proceeding to be closed to the extent necessary to prevent disclosure of matters occurring before a grand jury.(6) Sealed records. - All records relating to grand jury proceedings shall be kept under seal, unless the court orders disclosure.(f) Finding and return of indictment. - An indictment may be found only upon the concurrence of the requisite number of jurors in accordance with 10 Del. C. § 4505. The indictment shall be returned by the grand jury to a judge in open court.
