ORTH, J., delivered the opinion of the Court.
Appellant's only contention on this appeal is that his arrest was illegal and for that reason his oral confession and testimony that he was identified at a lineup were improperly admitted in evidence. He does not contend that the confession was not freely and voluntary given and the record discloses legally sufficient evidence for the trial court to find, as it did, that the "voluntariness test" was met. He does not allege that any rules of law enunciated by Escobedo v. Illinois, 378 U.S. 478 (1964) were violated. He is not within the ambit of Miranda v. Arizona, 384 U.S. 436, decided June 16, 1966 as Miranda is not retroactive. Meadows v. Warden, 243 Md. 710 (1966). He does not contend that there was anything improper in the conduct of the lineup. Appellant filed a Motion to Dismiss the information and indictment on the ground his arrest was illegal. The motion was properly denied by the trial court. An illegal arrest does not affect the jurisdiction of the court, is not a ground for dismissing an information or indictment and does not preclude trial and conviction for the offenses. Matthews v. State, 237 Md. 384 (1965). Although the confession and testimony that appellant was identified in a lineup were admitted in evidence without objection and therefore the question of their admission is not properly before us, we deem it desirable to consider the contention as the question of the legality of the arrest was raised below in the Motion to Dismiss. Maryland Rule, 1085.
The short answer is that the confession and testimony were properly admissible even if the arrest was illegal. Neither the confession nor the testimony in question were the fruits of an unreasonable search and seizure and being otherwise admissible
In any event, the arrest of appellant was lawful as he was arrested under a valid warrant. Bloombaum v. State, 237 Md. 663 (1965). Appellant contends that the warrant was invalid because facts presented to the issuing magistrate were not within the personal knowledge of the affiants and did not show probable cause. The warrant was issued by a committing magistrate, there is nothing in the record to indicate it was not valid on its face, and while we do not know exactly what the policemen swore to before the magistrate, the record does disclose that information obtained from the investigation of the case was presented to the magistrate. As it has not been shown that the officers did not have reasonable grounds for belief in the guilt of the appellant, this Court cannot hold that the arrest was unlawful. Scarlett v. State, 201 Md. 310 (1953). We know of no authority in this State that holds that facts to justify the issuance of a warrant of arrest must be within the personal knowledge of the affiant, provided that the magistrate is satisfied that there is probable cause for the issuance of the warrant. See Hochheimer, Law of Crimes and Criminal Procedure, § 89-94. We note that hearsay testimony is directly relevant and admissible on the issues of probable cause and the lawfulness of an arrest without a warrant. Farrow v. State, 233 Md. 526 (1964). We do not feel that evidence of probable cause for the issuance of an arrest warrant must be more stringent.
