Baron Johnson, a former Louisiana state prisoner, appearing pro se and in forma pauperis, appeals the district court’s dismissal of his civil action against various public officials, entities, and buildings. The district court dismissed Johnson’s complaint for failure to set forth a comprehensible cause of action. Johnson fails to provide a coherent argument that adequately addresses the district court’s analysis of this issue. See Fed. R.App. P. 28(a)(9); Yohey v. Collins, 985 F.2d 222, 224-25 (5th Cir. 1993); Brinkmann v. Dallas Cnty. Deputy Sheriff Abner, 813 F.2d 744, 748 (5th Cir. 1987). As Johnson has failed to adequately brief a challenge to the district court’s decision, his appeal is without arguable merit and, therefore, is dismissed as frivolous. See Howard v. King, 707 F.2d 215, 220 (5th Cir. 1983); 5th Cir. R. 42.2.

Johnson is warned that the filing of further frivolous appeals will result in sanctions. See Farguson v. MBank Houston, N.A., 808 F.2d 358, 359-60 (5th Cir. 1986). These sanctions may include dismissal, monetary sanctions, and restrictions on his ability to file pleadings in this court and any court subject to this court’s jurisdiction.

APPEAL DISMISSED; SANCTION WARNING ISSUED.
