MEMORANDUM **

California state prisoner Lafonzo Turner appeals pro se from the district court’s summary judgment in his 42 U.S.C. § 1983 action alleging that he was subjected to excessive force while a pretrial detainee at the Sacramento County Jail. We have jurisdiction under 28 U.S.C. § 1291. We review de novo summary judgment, Jones v. Blanas, 393 F.3d 918, 926 (9th Cir. 2004), *699 and for an abuse of discretion the denial of leave to amend, Caswell v. Calderon, 363 F.3d 832, 836 (9th Cir. 2004). We affirm.

The district court properly granted summary judgment because Turner failed to raise a genuine dispute of material fact as to whether he was in the custody of defendants when the alleged incident occurred. See Franklin v. Murphy, 745 F.2d 1221, 1235 (9th Cir. 1984) (to defeat summary judgment, a pro se litigant must present “significant probative evidence” to rebut that of defendants (citation and internal quotation marks omitted)). Moreover, Turner failed to raise a triable dispute as to whether any incident of alleged excessive force was the product of an official custom or practice or failure to train. See Monell v. Dep’t of Soc. Servs., 436 U.S. 658, 690-91, 98 S.Ct. 2018, 56 L.Ed.2d 611 (1978).

The district court did not abuse its discretion in denying Turner’s motion to file a second amended complaint under Fed. R.Civ.P. 15(a). See Lockheed Martin Corp. v. Network Solutions, Inc., 194 F.3d 980, 986 (9th Cir. 1999) (setting forth factors regarding whether to permit amendment).

The district court did not abuse its discretion in denying Turner’s requests for appointment of counsel. See Terrell v. Brewer, 935 F.2d 1015, 1017 (9th Cir. 1991) (setting forth standard of review and requiring “exceptional circumstances” for the appointment of counsel).

Turner’s contentions that the district court erred in denying his request for an injunction against a non-party and in failing to give adequate notice are unpersuasive.

Turner’s motion to supplement the pleadings is denied.

AFFIRMED.
