MEMORANDUM **

Robert Garber appeals pro se from the district court’s summary judgment in his 42 U.S.C. § 1988 action alleging various constitutional violations in connection with his arrest and detention. We have jurisdiction under 28 U.S.C. § 1291. We re-, view de novo a district court’s ruling on cross-motions for summary judgment, Guatay Christian Fellowship v. County of San Diego, 670 F.3d 957, 970 (9th Cir. 2011), and we affirm.

The district court properly granted summary judgment for defendants on Garber’s claim for false arrest because Garber failed to raise a genuine issue of material fact as to whether defendants lacked probable cause to arrest him. See Blankenhorn v. City of Orange, 485 F.3d 463, 470-71 (9th Cir. 2007) (explaining that a war-rantless arrest violates the Fourth Amendment if the arresting officer does not have probable cause to believe that person to be arrested has committed a felony, and describing the probable cause standard); compare Fed.R.Civ.P. 56 with Fed. R.Civ.P. 8 (describing different burdens for answers to complaints and motions for summary judgment).

We do not consider the district court’s summary judgment on Garber’s remaining claims. See Smith v. Marsh, 194 F.3d 1045, 1052 (9th Cir. 1999) (arguments not raised by a party in its opening brief are deemed waived).

The district court did not abuse its discretion in denying Garber leave to amend in order to add an additional defendant because defendants provided Garber with the name of the proposed defendant at least eight months before Garber sought leave to amend, and both parties had already moved for summary judgment. See United States v. Corinthian Colleges, 655 F.3d 984, 995 (9th Cir. 2011) (stating standard of review and factors for determining whether to grant leave to amend).

We reject as without merit Garber’s contentions of perjury and judicial bias.

AFFIRMED.
