    No. 09-2868.
    United States Court of Appeals, Eighth Circuit.
    Submitted: March 4, 2010.
    Filed: March 8, 2010.
    Before MELLOY, BOWMAN, and SMITH, Circuit Judges.
   PER CURIAM.

In this interlocutory appeal, Arkansas Department of Correction inmate Robert Maxwell challenges the order of the District Court denying his motion for a preliminary injunction. Upon careful review, we conclude that the District Court did not abuse its discretion in determining that a preliminary injunction was not warranted in this case. See 28 U.S.C. § 1292(a)(1) (giving courts of appeals jurisdiction of appeals from interlocutory orders refusing injunctions); Bandog, Inc. v. Jack’s Tire & Oil, Inc., 190 F.3d 924, 926 (8th Cir.1999) (per curiam) (standard of review). Maxwell did not allege sufficient facts to show a threat of irreparable harm resulting from the alleged threats and harassment, interference with his mail, or denial of his requests for library time. See Dataphase Sys., Inc. v. CL Sys., Inc., 640 F.2d 109, 113, 114 n. 9 (8th Cir.1981) (en banc) (holding that whether a preliminary injunction should issue involves consideration of, in--ter alia, the threat of irreparable harm and noting that lack of a threat of irreparable injury is a sufficient reason to deny a preliminary injunction); see also Goff v. Harper, 60 F.3d 518, 520 (8th Cir.1995) (explaining that a request for injunctive relief in the prison context is “viewed with '■ great caution” because of the particular problems of prison administration).

Accordingly, we affirm. 
      
      . The Honorable James M. Moody, United States District Judge for the Eastern District of Arkansas, adopting the report and recommendations of the Honorable H. David Young, United States Magistrate Judge for the Eastern District of Arkansas.
