If an informant's information is sufficient to establish probable cause for arrest, is that information sufficient to warrant arrest?

2 Defendant also contends his arrest was illegal. If, however, the informant's information was sufficiently reliable to support the issuance of a search warrant, it was also sufficient to establish probable cause for defendant's arrest. (Skelton v. Superior Court (1969) 1 Cal.3d 144, 150, 81 Cal.Rptr. 613, 460 P.2d 485.)

3 People v. Gastelo (1967) supra, 67 Cal.2d 586, 63 Cal.Rptr. 10, 432 P.2d 706, emphasized that compliance with announcement requirements could be excused only on the basis of specific facts and not on the basis of blanket presumptions.
