PER CURIAM.

        Timothy Watkins appeals the district court’s adverse grant of summary
judgment in his 42 U.S.C. § 1983 action against Arkansas Highway Police (AHP)
officers Brad Perkins and David Smith, and Billy’s Trucking (Billy’s), a towing
company, arising from an incident in which he was stopped while driving a tractor-
trailer in Arkansas for following too close. We affirm in part and reverse in part.
       This court reviews de novo the grant of summary judgment, viewing the record
and all reasonable inferences from it in a light most favorable to Watkins. See Mack
v. Dillon, 

, 622 (8th Cir. 2010) (per curiam). We conclude that the AHP
officers failed to meet their burden as summary judgment movants. See Carrington
v. City of Des Moines, Iowa, 

, 1050-51 (8th Cir. 2007) (at summary-
judgment stage, moving parties carry ultimate burden of proof to establish no material
facts are in dispute). Specifically, in finding that the material facts as to the officers’
actions were undisputed and that they had not violated Watkins’s constitutional
rights, it appears that the district court considered the officers’ unauthenticated and
unsigned memoranda, as well as the other unauthenticated documents they offered,
although those materials would not be admissible in evidence. See Shanklin v.
Fitzgerald, 

, 602 (8th Cir. 2005) (summary judgment documents must
be authenticated by and attached to affidavit made on personal knowledge setting
forth such facts as would be admissible in evidence or deposition, and documents not
meeting such requirements cannot be considered). For purposes of his Fourth
Amendment claims against the officers, while Watkins admitted not signing the
citation for following too close, there was a genuine issue of material fact as to
whether the officers had a reasonable suspicion or probable cause to stop him for such
a violation–especially given his testimony that he had not even seen the truck
carrying logs he was charged with following too close. See United States v. Houston,

, 1153 (8th Cir. 2008) (traffic stop is seizure within meaning of Fourth
Amendment and thus must be supported by reasonable suspicion or probable cause);
Kurtz v. City of Shrewsbury, 

, 755-58 (8th Cir. 2001) (in case where
plaintiff was arrested for tampering with car and driving without license, noting that
false arrest claim required showing arrest was made without probable cause).

       Further, although the admissible evidence showed that Watkins did not own
the tractor-trailer or its contents, he had standing to assert a claim based on the towing
of the tractor-trailer, because he testified as to the adverse consequences to him from
the towing, arising from the fact that as an employee of A & H Cartage LLC, he was

                                           -2-
responsible for the tractor-trailer and its contents. See Turkish Coalition of Am., Inc.
v. Bruininks, 

, 621 (8th Cir. 2012) (standing requires injury that is
particularized and concrete and actual, not merely conjectural, that is fairly traceable
to action of defendant, and that is likely to be redressed by favorable decision); see
also United States v. Jacobsen, 

, 113 (indicating a "seizure" of property
occurs "when there is some meaningful interference with an individual's possessory
interest in that property."); United States v. Fuller, 

, 621 (8th Cir. 2007)
("It is important to realize that a person's interest in his or her loaned effects is not
identical to the possessory interest of the bailee [i.e., Watkins] who has direct control
of the effects, and the lender cannot assert the bailee's independent Fourth
Amendment right to have the bailee's interest protected from unreasonable
government interference."). Thus, a genuine issue of material fact remained as to
whether there was reasonable suspicion or probable cause for the stop, and because
he would not have been arrested and the tractor-trailer towed absent the stop, there
is also a jury issue on the Fourth Amendment claim arising from the towing. See
Alman v. Reed, 

, 903-04 (6th Cir. 2013) (seizure of vehicle in
connection with arrest not supported by probable cause violates Fourth Amendment
in same manner that arrest itself violates Fourth Amendment).

       We find no basis for overturning the grant of summary judgment to Billy’s,
given that Watkins testified in his deposition that Billy’s was not involved in the
matters giving rise to the damages at issue in the instant suit, and the fact that
Arkansas has adequate post-deprivation remedies for the loss of Watkins’s personal
property during the period Billy’s stored the tractor-trailer. See Willis Smith & Co.
v. Arkansas, 

, 640 (8th Cir. 2008). Finally, we find no abuse of
discretion in the district court’s denial of Watkins’s motions for leave to amend. See
Popoalii v. Corr. Med. Servs., 

, 497 (8th Cir. 2008) (court does not
abuse its discretion when it denies motion to amend where there is undue delay or
undue prejudice to non-moving party).



                                          -3-
      Accordingly, we reverse the grant of summary judgment on the Fourth
Amendment claims for false arrest and seizure of property against the officers, and
remand for further consideration of these claims; and in all other respects we affirm.
On remand the district court may wish to reconsider whether appointment of counsel
is warranted.
