Can a search warrant be used to search a car that was ordered by a police officer on a radio message?

Appellant nevertheless challenges the search on the ground that the officer who received the radio message to arrest the appellant and who stopped the car and began a car search, did not have knowledge of all of the circumstances that had given rise to the arrest order. Appellant contends that in the absence of personal knowledge of probable cause, the arresting officer engaged in an improper "inventory" search. We need not determine the validity of the inventory search, however, because it is clear that the collective knowledge of the officers involved in the investigation may be considered in determining whether there was probable cause to support a warrantless search of an automobile. See United States v. Bernard, 623 F.2d 551, 560-1 (9th Cir.1979) (separate facts known to several officers can be accumulated to meet probable cause requirement).
