We affirm the trial court order summarily denying appellant’s third motion for post-conviction relief and/or habeas corpus petition. This motion was unsworn, untimely, successive and patently without merit. Appellant filed two prior motions for post-conviction relief, the summary denial of which this court affirmed per curiam in Lewin v. State, 881 So.2d 1124 (Fla. 4th DCA 2004), and Lewin v. State, 901 So.2d 138 (Fla. 4th DCA 2005).

Accordingly, we caution appellant that the filing of any future successive and frivolous pro se motions, petitions or appeals attacking his convictions and sentences in this case may result in sanctions, such as a ban on future pro se filings in this court and/or referral to prison officials for disciplinary procedures. See State v. Spencer, 751 So,2d 47 (Fla. 1999). See also § 944.279(1), Fla. Stat.; Fla. R. Crim. P. 3.850(n).

Affimied.
