Can a police officer make an arrest for a criminal charge without a warrant?

The complaint alleges that respondents arrested appellant because he was charged with a felony. True, no complaint had been filed against him, but the filing of a formal charge was not necessary if the officers believed appellant's arrest was their duty. People v. Serrano, 123 Cal.App. 339, 341, 11 P.2d 81. So important to the peace and security of society is the apprehension of evildoers that an arrest by peace officers for a felony without a warrant is authorized. People v. Garnett, 129 Cal. 364, 366, 61 P. 1114. In fact, the officer is commanded by law to make an arrest for a felony where public security is imperiled by the freedom of the suspect.
