Tracy Adam Thompson (Thompson) appeals the district court’s 1 preservice dismissal of his 42 U.S.C. § 1983 complaint. Upon de novo review, see Moore v. Sims, 200 F.3d 1170, 1171 (8th Cir. 2000) (per curiam) (standard of review), we conclude dismissal was proper. The sheriffs office generally is not a suable entity under § 1983, and Thompson did not allege any *481 official policy or widespread practice or custom of the sheriffs office which deprived him of his constitutional rights. We affirm the judgment of the district court. See 8th Cir. R. 47B.
